Answer:3.1875

Step-by-step explanation: Simplifying

-3 + 8 + - 8 (7 + - 2a) = 0

-3 + 8 + (7 * - 8 + - 2a * - 8) = 0

-3 + 8 + (-56 + 16a) = 0

Combine like terms: - 3 + 8 = 5

5 + - 56 + 16a = 0

Combine like terms: 5 + - 56 = - 51

-51 + 16a = 0

Solving

-51 + 16a = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '51' to each side of the equation.

-51 + 51 + 16a = 0 + 51

Combine like terms: - 51 + 51 = 0

0 + 16a = 0 + 51

16a = 0 + 51

Combine like terms: 0 + 51 = 51

16a = 51

Divide each side by '16'.

a = 3.1875

Simplifying

a = 3.1875
