Simplifying 7r + 3(7 + r) = -1(r + 4) 7r + (7 * 3 + r * 3) = -1(r + 4) 7r + (21 + 3r) = -1(r + 4) Reorder the terms: 21 + 7r + 3r = -1(r + 4) Combine like terms: 7r + 3r = 10r 21 + 10r = -1(r + 4) Reorder the terms: 21 + 10r = -1(4 + r) 21 + 10r = (4 * -1 + r * -1) 21 + 10r = (-4 + -1r) Solving 21 + 10r = -4 + -1r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add 'r' to each side of the equation. 21 + 10r + r = -4 + -1r + r Combine like terms: 10r + r = 11r 21 + 11r = -4 + -1r + r Combine like terms: -1r + r = 0 21 + 11r = -4 + 0 21 + 11r = -4 Add '-21' to each side of the equation. 21 + -21 + 11r = -4 + -21 Combine like terms: 21 + -21 = 0 0 + 11r = -4 + -21 11r = -4 + -21 Combine like terms: -4 + -21 = -25 11r = -25 Divide each side by '11'. r = -2.272727273 Simplifying r = -2.272727273
