Simplifying 12 = -3(2 + 2r) + -1(2r + 2) 12 = (2 * -3 + 2r * -3) + -1(2r + 2) 12 = (-6 + -6r) + -1(2r + 2) Reorder the terms: 12 = -6 + -6r + -1(2 + 2r) 12 = -6 + -6r + (2 * -1 + 2r * -1) 12 = -6 + -6r + (-2 + -2r) Reorder the terms: 12 = -6 + -2 + -6r + -2r Combine like terms: -6 + -2 = -8 12 = -8 + -6r + -2r Combine like terms: -6r + -2r = -8r 12 = -8 + -8r Solving 12 = -8 + -8r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '8r' to each side of the equation. 12 + 8r = -8 + -8r + 8r Combine like terms: -8r + 8r = 0 12 + 8r = -8 + 0 12 + 8r = -8 Add '-12' to each side of the equation. 12 + -12 + 8r = -8 + -12 Combine like terms: 12 + -12 = 0 0 + 8r = -8 + -12 8r = -8 + -12 Combine like terms: -8 + -12 = -20 8r = -20 Divide each side by '8'. r = -2.5 Simplifying r = -2.5
