solve the linear system using any algebraic method 8x - 6y = 14 and 12x -9y = 18

8x-6y=14,12x-9y=18 Multiply each equation by the value that makes the coefficients of y equal.  This value is found by dividing the least common multiple of the coefficients of y by the current coefficient.  In this case, the least common multiple is 18. 3*(8x-6y=14)_2*(12x-9y=18) Multiply each equation by the value that makes the coefficients of y equal.  This value is found by dividing the least common multiple of the coefficients of y by the current coefficient.  In this case, the least common multiple is 18. 3*(8x-6y)=3(14)_2*(12x-9y)=2(18) Multiply 3 by each term inside the parentheses. 3*(8x-6y)=42_2*(12x-9y)=2(18) Multiply 3 by each term inside the parentheses. (24x-18y)=42_2*(12x-9y)=2(18) Remove the parentheses around the expression 24x-18y. 24x-18y=42_2*(12x-9y)=2(18) Multiply 2 by each term inside the parentheses. 24x-18y=42_2*(12x-9y)=36 Multiply 2 by each term inside the parentheses. 24x-18y=42_(24x-18y)=36 Remove the parentheses around the expression 24x-18y. 24x-18y=42_24x-18y=36 Multiply the first equation by -1 to make the coefficients of y have opposite signs. -(24x-18y)=-(42)_24x-18y=36 Multiply -1 by the 42 inside the parentheses. -(24x-18y)=-42_24x-18y=36 Multiply -1 by each term inside the parentheses. (-24x+18y)=-42_24x-18y=36 Remove the parentheses around the expression -24x+18y. -24x+18y=-42_24x-18y=36 Add the two equations together to eliminate y from the system.  24x-18y=36_-24x+18y=-42_        =- 6 Since 0$-6, there are no solutions. No Solution The system cannot be solved because it is inconsistent and has no intersection. The system cannot be solved because it is inconsistent.

please help with describing and ordering fractions

The divisions between 0 and 1 show how a fraction is made up. Let's take the case where the interval is divided up into 12 equal divisions. One division represents 1/12. Two divisions represent 2/12 which together represent 1/6 because 6*2=12 and the interval between 0 and 1 contains 6 sixths. Three divisions represent 3/12 which represent 1/4 because 4*3=12 and the interval between 0 and 1 contains 4 fourths or quarters, just like there are four quarters to $1. Four divisions represent 4/12 or one third. Five divisions just represent 5/12 and 7 divisions represent 7/12; but 6 divisions represent 6/12 or one half and two lots of these make 1. So 2*6/12 is the same as 2*1/2. 11 divisions make 11/12. Eight divisions is 8/12. Since 4/12 is a third, 8/12 must be two thirds because 2*4=8 or 2*4/12=8/12. Nine divisions are 3*3/12=9/12, and since 3/12 is the same as a quarter, 9/12 must be three quarters. Ten divisions make 10/12, but since 5*2/12=10/12 and 2/12 is one sixth, 10/12 must be 5 sixths or 5/6. If the interval 0 to 1 is divided into 60 divisions we get more fractions. The divisions help us to add and subtract. The number of divisions is associated with the least common multiple (LCM). So the LCM of 2, 3, 4 and 6 is 12. For 60 as LCM we have 2, 3, 4, 5, 6, 10, 12, 15, 20, 30. These numbers of divisions give us the fractions 1/30, 1/20, 1/15, 1/12, 1/10, 1/6, 1/5, 1/4, 1/3, 1/2. So to add 1/5 and 1/6 we use the divisions 12/60+10/60=22/60=11/30 because 22=2*11 and 22/60=2*11/60=11/30. We can also see that 11/30-1/5 is the same as 22/60-12/60=10/60=1/6. This should give you some idea how dividing 0 to 1 into different divisions helps you see how fractions add and subtract.

Is V vactor space

If the product abcd=0, then we know at least one of a, b, c, d is zero. Therefore the set would include the zero matrix, in which a=b=c=d=0, as well as all combinations of a, b, c, d where at least one is zero. ADDITION The implication is that V is not closed under addition because the result of adding two matrices in V is: ( a1 b1 ) + (a2 b2 ) = ( a1+a2 b1+b2 ) ( c1 d1 )    ( c2 d2 )   ( c1+c2 d1+d2 ) Unless corresponding elements in the matrices on the left produce at least one zero in an element on the right, the sum will not belong to V. So a1+a2=0, making a2=-a1 or b1+b2=0, etc. So in the general case V is not closed under addition. If, for example, a1=0=b2 but no other element is zero, the sum will contain no zero elements. MULTIPLICATION Matrix multiplication gives us: ( a1a2+b1c2 a1b2+b1d2 ) ( c1a2+d1c2 c1b2+d1d2 ) Again, at least one element in the matrix product must be zero in order to qualify for membership of V. Therefore V is not closed under matrix multiplication. V is closed under scalar multiplication, because zero elements remain zero. My guess is that V is not a vector subspace since matrix addition and matrix multiplication are excluded in general between the elements of the set. The identity vector, like the zero vector, appears to be an element in the set because the matrix contains two zero elements.

what is the greatest multiple of 45 811 and 63

the greatest multiple would be infinity   If you mean the greatest common factor: 45 = 3 * 3 * 5 63 = 3 * 3 * 7 81 = 3 * 3 * 3 * 3 they all have 3 * 3 in common the greatest common factor is 3 * 3 = 9   if you mean the least common multiple: 45 = 3 * 3 * 5 63 = 3 * 3 * 7 81 = 3 * 3 * 3 * 3 the least common multiple is 3 * 3 * 3 * 3 * 5 * 7 because that has all the parts needed to make each of the three numbers 3 * 3 * 3 * 3 * 5 * 7 = 2835
