Question

x+3[1-x]-4 = -4[´x-1] - [2x -95]

Answer 1

x + 3.(1 - x) - 4 = - 4.(x - 1) - (2x - 95)
x + 3 - 3x - 4 = - 4x - 4 - 2x + 95
x - 3x + 3 - 4 = - 4x - 2x - 4 + 95
- 2x - 1 = - 6x + 91
- 2x + 6x = 91 + 1
4x = 92
x = $\frac{92}{4}$
x = 23

Bons estudos

Answer 2

x+3-3x-4=-4x +4-2x+95
x+3-3x-4=-4x+4-2x+95
x-3x+4x+2x=+4+95-3+4
-2x+6x=96-3+4
4x=100
x=25
