5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )

3x+2=2x+8x=63x+2 = 2x + 8; first subtract 2x from both sidesx+2=8; then subtract 2 from both sidesx=6

-7 +2x = x + 8 2x - x = 7 + 8 x = 15

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

This is not Calculus. 6 + (2*4 = 8) = 14.

X=7
