x = 5
==========
3x - 9 = -2x + 16
Balance the equation by adding 2x and 9 to both sides:
3x + 2x = 16 + 9
5x = 25
Divide both sides by 5 to get value for x:
x = 5

-5x+3(x+8)=16-2x
3x+56 = 2x+4 3x-2x = 4-56 x = -52
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
2x + 2 = 3x - 57 = x
