3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20

3x+56 = 2x+4 3x-2x = 4-56 x = -52
2x2 + 3x - 20 = (x + 4)(2x - 5).
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
2x+3x = 5x
balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7
1 + x + 2x = 20 So 1 + 3x = 20 so that 3x = 19 then x = 19/3 or 61/3

3x+5 = 2x+13 3x-2x = 13-5 x = 8
3x+56 = 2x+4 3x-2x = 4-56 x = -52

2x2 + 3x - 20 = (x + 4)(2x - 5).
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
2x + 20 = 3x20 = 3X - 2X20 = X
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
