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
