2x + 8 = 3x - 4
Subtract 2x from both sides: 8 = x - 4
Add 4 to both sides: 12 = x

no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
X=7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
