-4x+1-2(x-1)= -4(x-4)
-4x + 1 - 2x + 2 = -4x + 16
-6x + 3 = -4x + 16
-2x = 13
x = -6.5
- 4 x + 1 - 2 ( x - 1 ) = - 4 ( x - 4 )
- 4 x + 1 - 2 * x - 2 * ( - 1 ) = - 4 * x - 4 * ( - 4 )
- 4 x + 1 - 2 x + 2 = - 4 x + 16
- 4 x - 2 x + 1 + 2 = - 4 x + 16
- 6 x + 3 = - 4 x + 16
- 6 x + 4 x = 16 - 3
- 2 x = 13 Divide both sides by - 2
x = 13 / - 2 = - 13 / 2
x = - 6.5
