Simplifying
(V + 7)(v + -9) = 0

Reorder the terms:
(7 + V)(v + -9) = 0

Reorder the terms:
(7 + V)(-9 + v) = 0

Multiply (7 + V) * (-9 + v)
(7(-9 + v) + V(-9 + v)) = 0
((-9 * 7 + v * 7) + V(-9 + v)) = 0
((-63 + 7v) + V(-9 + v)) = 0
(-63 + 7v + (-9 * V + v * V)) = 0
(-63 + 7v + (-9V + vV)) = 0

Reorder the terms:
(-63 + -9V + 7v + vV) = 0
(-63 + -9V + 7v + vV) = 0

Solving
-63 + -9V + 7v + vV = 0

Solving for variable 'V'.

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