$a = - 2$

Step-by-step explanation:

1) Subtract 8 from both sides.

$- 3a = 14 - 8$

2) Simplify 14 - 8 to 6.

$- 3a = 6$

3) Divide both sides by, -3.

$a = - \frac{6}{3}$

4) Simplify 6/3 to 2.

$a = - 2$

Therefor, the answer is, a = -2.

kramer

Step 1. Simplify
7x^2 - 8x - 4 - 2x^2 + 3x + 5 + 5x^2 - 10x - 8
Step 2. Collect like terms
(7x^2 - 2x^2 + 5x^2) + (-8x + 3x - 10x) + (-4 + 5 - 8)
Step 3. Simplify

10x^2 - 15x - 7
