please help me solve 1/2(x+1)=1/3(x-1)

please help me solve 1/2(x+1)=1/3(x-1) please help me solve thie equation showing work 1/2(x + 1) = 1/3(x - 1) 6(1/2(x + 1)) = 6(1/3(x - 1)) 3(x + 1) = 2(x - 1) 3x + 3 = 2x - 2 x = -5 Check it. 1/2(x + 1) = 1/3(x - 1) 1/2(-5 + 1) = 1/3(-5 - 1) 1/2(-4) = 1/3(-6) -2 = -2

How do you solve this problem? solve for d: n= m+3d/4

Problem: How do you solve this problem? solve for d: n= m+3d/4 I need help solving this and seeing how it was solved since I am having trouble figuring out what to do and how to solve it thanks. n = m + 3d/4 n - m = (m + 3d/4) - m n - m = 3d/4 4(n - m) = (3d/4)4 4(n - m) = 3d 4(n - m)/3 = 3d/3 4/3 (n - m) = d Answer: d = 4/3 (n - m)

-4d + 2e + f= -20

-4d + 2e + f = -20 pleasee help meeeee There is nothing you can do with this. When you have more than one unknown (one variable), you need more than one equation. You manipulate the equations by multiplying them so two of them have the same co-efficient for one of the variables. Then, you add or subtract those equations to eliminate the variable. Keep doing that until you have one equation with only one variable. Solve that equation and plug the value into one of the equations to solve for another variable. Keep adding and subtracting equations to isolate one of the variables, solve for it, and use that to help solve another equation. One equation with two or more variables is a lost cause.

How to solve (3x+22)=(6x-8)?

How to solve (3x+22)=(6x-8)? Our lesson is now about Parallel Lines and we have to solve first before using the theorems. And I don't know how to solve it. Please help me. Oh, and the teacher said thar the working equations is m<1 = m<2. Thank you so much 3x + 22 = 6x - 8 3x + 22 - 3x = 6x - 8 - 3x 22 = 3x - 8 22 + 8 = 3x - 8 + 8 30 = 3x 30 / 3 = 3x / 3 10 = x

using the elimination method solve 6=6x+6y and -14y=18x+14

using the elimination method solve 6=6x+6y and -14y=18x+14 help me solve step by step 1) 6 = 6x + 6y 2) -14y = 18x + 14 Re-write equation 1: 3) 6x + 6y = 6 It is standard to have the unknowns of the left side of the equation. Now, for equation 2. -14y = 18x + 14 4) -18x - 14y = 14 Multiply equation 3 by 3. 3 * (6x + 6y) = 6 * 3 5) 18x + 18y = 18 Add equation 4 to equation 5.    18x + 18y = 18 +(-18x - 14y = 14) -------------------           4y = 32 You have just eliminated the x. Solve for y. 4y = 32 y = 8 You can used either equation 1 or equation 2 to solve for x. 1) 6 = 6x + 6y = 6    6x + 6(8) = 6    6x + 48 = 6    6x = 6 - 48    6x = -42    x = -7 Check it with equation 2. 2) -14y = 18x + 14    -14(8) = 18(-7) + 14    -112 = -126 + 14    -112 = -112 You have x = -7 and y = 8

need help in solving for x ?

2x - 7 = -x + 2 add 2 to both sides: 3x - 7 = 2 add 7 to both sides: 3x = 9 divide both sides by 3: x = 9/3 = 3   -2 - 3x = x + 6 subtract x from both sides: -2 - 4x = 6 add 2 to both sides: -4x = 8 divide both sides by -4: x = 8/-4 = -2

Help needed in understanding the process to solve a trig problem such as [ 2sin^2x-3x= 0 ]

  Remember the relation between sine and cosine? sine^2+cosine^2=1, so sin^2X=1-cos^2X. Substitute for sin^2X: 2(1-cos^2X)-3cosX=0; 2-2cos^2X-3cosX=0. We now have a quadratic equation. If it helps, let y= cosX, then: 2-2y^2-3y=0 or 2y^2+3y-2=0, which factorises: (2y-1)(y+2)=0, and y=1/2 or -2 which means cosX=1/2 or -2. But we know that cosX can't be bigger than 1 or less than -1, so we can safely reject cosX=-2, and solve cosX=1/2. This is one of those familiar angles, X=60 degrees or (pi)/3 radians. Now you need to remember which quadrants cosine is positive in. ASTC (All Silver Tea Cups: All trigs, sin, tan, cos) for Q1 to 4. So cosine is positive in Q1 and Q4. The solution therefore is (pi)/3 and 2(pi)-(pi)/3=5(pi)/3 or 60 and 360-60=300 degrees.
