Simplifying 4 = -2(v + -1) Reorder the terms: 4 = -2(-1 + v) 4 = (-1 * -2 + v * -2) 4 = (2 + -2v) Solving 4 = 2 + -2v Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2v' to each side of the equation. 4 + 2v = 2 + -2v + 2v Combine like terms: -2v + 2v = 0 4 + 2v = 2 + 0 4 + 2v = 2 Add '-4' to each side of the equation. 4 + -4 + 2v = 2 + -4 Combine like terms: 4 + -4 = 0 0 + 2v = 2 + -4 2v = 2 + -4 Combine like terms: 2 + -4 = -2 2v = -2 Divide each side by '2'. v = -1 Simplifying v = -1
