Question

me ayudan 3(1-2x)+12=10-2(x-3)

-2(x+3)-4=18+4x

2(3x+1)-x+6=2(x-1)

Answer 1

3(1-2x)+12=10-2(x-3)
3 - 6 x + 12 = 10 - 2 x + 6
- 6 x + 2 x   = 10 + 6 - 3
          - 4 x  = 13
              x   =  - 13/4

-2(x+3)-4=18+4x
- 2 x - 6 - 4 = 18 + 4 x
- 2 x - 4 x   =  18 + 6 + 4
        - 6 x   = 28
             x = - 28/ 6
             x = - 14/3


2(3x+1)-x+6=2(x-1)

6 x + 2 - x + 6 = 2 x - 2
6 x - x - 2 x     = - 2 - 2 - 6
             3 x = - 10
                x = - 10/3
