4x + -x = 3x
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
5x - 4x = x
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
If you mean 5x+4x = 54 then the value of x is 6
-1
4x
5x = 4x + 9 x = 9
4x-7=5x-2 x=-5
5x+12 = 4x-88 x = -100
5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9
