Question

3(-4x -3) + 5x -5 = 0
Solve for x

Answer 1

`x = - 2`

Explanation:

1) Expand.

`- 12x - 9 + 5x - 5 = 0`

2) Simplify 12x - 9 + 5x - 5 to -7x -14.

`- 7x - 14 = 0`

3) Add 14 to both sides.

`- 7x = 14`

4) Divide both sides by -7.

`x = - (14)/(7)`

5) Simplify 14/7 to 2.

`x = - 2`

Therefor, the answer is x = -2.

Answer 2

-2

Explanation:

3(-4x-3) + 5x -5 = 0

-12x -9 + 5x -5 = 0

-7x -14 = 0

-7x = 14

-7x/-7 = 14/-7

x= -2
