3(4x+2) - 6x = 5x - 5(2 + x)
3·4x+3·2-6x=5x-5·2-5·x
12x+6-6x=5x-10-5x
12x-6x-5x+5x= -10-6
6x=-16

x=- (16)/(6) \\ x=- (8)/(3) \\ x=-2 (2)/(3)

3(4x + 2) - 6x = 5x - 5(2 + x)

First, expand the equation. / Your problem should look like: 12x + 6 - 6x = 5x - 10 - 5x
Second, simplify 12x + 6 - 6x to 6x + 6. / Your problem should look like: 6x + 6 = 5x - 10 - 5x
Third, simplify 5x - 10 - 5x to -10. / Your problem should look like: 6x + 6 = -10
Fourth, subtract 6 from both sides. / Your problem should look like: 6x = -10 - 6
Fifth, simplify -10 - 6 to -16. / Your problem should look like: 6x = -16
Sixth, divide both sides by 6. / Your problem should look like: x =
-(16)/(6)
Seventh, simplify
(16)/(6) to
(8)/(3) / Your problem should look like: x =
- (8)/(3)

Answer: x =
- (8)/(3)
