-2x+14=20 x=-3

-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4

It is simply 2x+20 which is an algebraic expression that has no equality sign.

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

If: 3x+20 = 2x-10 Then: x = -30

Find the value of 'x' when 2x+8=4x+20 First subtract '2x' from both sides. 8=2x+20 Then subtract '20' from each side. -12=2x Then divide each side by '2' -6=x. Therefore 'x=-6'
