Simplifying 2(-2 + 4) = -2(r + 5) Combine like terms: -2 + 4 = 2 2(2) = -2(r + 5) Multiply 2 * 2 4 = -2(r + 5) Reorder the terms: 4 = -2(5 + r) 4 = (5 * -2 + r * -2) 4 = (-10 + -2r) Solving 4 = -10 + -2r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '2r' to each side of the equation. 4 + 2r = -10 + -2r + 2r Combine like terms: -2r + 2r = 0 4 + 2r = -10 + 0 4 + 2r = -10 Add '-4' to each side of the equation. 4 + -4 + 2r = -10 + -4 Combine like terms: 4 + -4 = 0 0 + 2r = -10 + -4 2r = -10 + -4 Combine like terms: -10 + -4 = -14 2r = -14 Divide each side by '2'. r = -7 Simplifying r = -7
