Answer:

-2

Step-by-step explanation:

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

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

-7x -14 = 0

-7x = 14

-7x/-7 = 14/-7

x= -2

Answer:

[tex]x = - 2[/tex]

Step-by-step explanation:

1) Expand.

[tex] - 12x - 9 + 5x - 5 = 0[/tex]

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

[tex] - 7x - 14 = 0[/tex]

3) Add 14 to both sides.

[tex] - 7x = 14[/tex]

4) Divide both sides by -7.

[tex]x = - \frac{14}{7} [/tex]

5) Simplify 14/7 to 2.

[tex]x = - 2[/tex]

Therefor, the answer is x = -2.
