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.
