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

3x+8 = 12 3x = 4 x = 4/3

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

3x-6y=-8

8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3

2x2+6x-8 = 72 2x2+6x-8-72 = 0 2x2+6x-80 = 0 (2x-10)(x+8) = 0

3x - 8 = 7 so x = 5

3x + 2y = 8 This is an equation. It could be the equation of a line.
