Simplifying 2r + -1(5 + r) = 13 + 2r 2r + (5 * -1 + r * -1) = 13 + 2r 2r + (-5 + -1r) = 13 + 2r Reorder the terms: -5 + 2r + -1r = 13 + 2r Combine like terms: 2r + -1r = 1r -5 + 1r = 13 + 2r Solving -5 + 1r = 13 + 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. -5 + 1r + -2r = 13 + 2r + -2r Combine like terms: 1r + -2r = -1r -5 + -1r = 13 + 2r + -2r Combine like terms: 2r + -2r = 0 -5 + -1r = 13 + 0 -5 + -1r = 13 Add '5' to each side of the equation. -5 + 5 + -1r = 13 + 5 Combine like terms: -5 + 5 = 0 0 + -1r = 13 + 5 -1r = 13 + 5 Combine like terms: 13 + 5 = 18 -1r = 18 Divide each side by '-1'. r = -18 Simplifying r = -18
