Answer:
Simplifying
7(q + 2) = -77
Reorder the terms:
7(2 + q) = -77
(2 * 7 + q * 7) = -77
(14 + 7q) = -77
Solving
14 + 7q = -77
Solving for variable 'q'.
Move all terms containing q to the left, all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + 7q = -77 + -14
Combine like terms: 14 + -14 = 0
0 + 7q = -77 + -14
7q = -77 + -14
Combine like terms: -77 + -14 = -91
7q = -91
Divide each side by '7'.
q = -13
Simplifying
q = -13
