Suggested Questions And Answer :


5(2x + 1) = 12x – 1

5(2x + 1) = 12x - 1 10x + 5 = 12x - 1   Now you can subtract 5 from both sides of the equation: 10x + 5 - 5 = 12x - 1 - 5 10x = 12x - 6   Now you can subtract '12x' from both sides of the equation: 10x - 12x = 12x - 6 - 12x - 2x = - 6   Now you can divide both sides of the equation by ' -2 ' to find the value of 'x' on it's own: (- 2x)/(-2) = (- 6)/(-2) x = 6/2 = 3   So the final answer is x = 3 .

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.

Solve the second order ordinary differential equation y"-4y=12x y(0)=4 and y'(0)=1?

y"-4y=12x. Let y=p+q where p and q are functions of x, then y"=p"+q". So p"+q"-4p-4q=12x. If p"-4p=0 can be solved we only have to solve q"-4q=12x. p"-4p=0 has the characteristic equation (m-2)(m+2)=0 and we use the roots to suggest what p might be: p=Ae^2x+Be^-2x; p'=2Ae^2x-2Be^2x; p"=4Ae^2x+4Be^2x=4p. Now for q. Since q"=0, q'=a, a constant, and q=ax+b. q"-4q must be equal to 12x so -4ax-4b=12x, making b=0 and a=-3. Therefore q=-3x and y=p+q=Ae^2x+Be^-2x-3x; y'=2Ae^2x-2Be^2x-3. y(0)=4=A+B; y'(0)=1=2A-2B-3, A-B=2. So 2A=6, A=3 and B=1. y=3e^2x+e^-2x-3x.
