Simplifying -1(-1r + 1) = -3(-7 + 4r) Reorder the terms: -1(1 + -1r) = -3(-7 + 4r) (1 * -1 + -1r * -1) = -3(-7 + 4r) (-1 + 1r) = -3(-7 + 4r) -1 + 1r = (-7 * -3 + 4r * -3) -1 + 1r = (21 + -12r) Solving -1 + 1r = 21 + -12r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '12r' to each side of the equation. -1 + 1r + 12r = 21 + -12r + 12r Combine like terms: 1r + 12r = 13r -1 + 13r = 21 + -12r + 12r Combine like terms: -12r + 12r = 0 -1 + 13r = 21 + 0 -1 + 13r = 21 Add '1' to each side of the equation. -1 + 1 + 13r = 21 + 1 Combine like terms: -1 + 1 = 0 0 + 13r = 21 + 1 13r = 21 + 1 Combine like terms: 21 + 1 = 22 13r = 22 Divide each side by '13'. r = 1.692307692 Simplifying r = 1.692307692
