Simplifying -20 = -4(1 + -3r) + -2(4r + -4) -20 = (1 * -4 + -3r * -4) + -2(4r + -4) -20 = (-4 + 12r) + -2(4r + -4) Reorder the terms: -20 = -4 + 12r + -2(-4 + 4r) -20 = -4 + 12r + (-4 * -2 + 4r * -2) -20 = -4 + 12r + (8 + -8r) Reorder the terms: -20 = -4 + 8 + 12r + -8r Combine like terms: -4 + 8 = 4 -20 = 4 + 12r + -8r Combine like terms: 12r + -8r = 4r -20 = 4 + 4r Solving -20 = 4 + 4r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-4r' to each side of the equation. -20 + -4r = 4 + 4r + -4r Combine like terms: 4r + -4r = 0 -20 + -4r = 4 + 0 -20 + -4r = 4 Add '20' to each side of the equation. -20 + 20 + -4r = 4 + 20 Combine like terms: -20 + 20 = 0 0 + -4r = 4 + 20 -4r = 4 + 20 Combine like terms: 4 + 20 = 24 -4r = 24 Divide each side by '-4'. r = -6 Simplifying r = -6
