Question

5.(3x+2)-6(.2x+4)=40+15x

Answer 1

15x+10-12x-24=40+15x
15x-12x+10-24=40+15x
3x-14=40+15x
3x-15x=40+14
-12x=54
x=54/-12
x= -4,5

Answer 2

5.(3x + 2) - 6(.2x + 4) = 40 + 15x

15x + 10 - 12x - 24 = 40 + 15x

10 - 24 - 12x = 40

- 14 - 12x = 40

- 14 - 40 = 12x

- 54 = 12x

12x = - 54

x = - 54  (:2)  =  - 27
        12  (:2)         6
