Simplifying 3(r + 1) = -4(r + -4) Reorder the terms: 3(1 + r) = -4(r + -4) (1 * 3 + r * 3) = -4(r + -4) (3 + 3r) = -4(r + -4) Reorder the terms: 3 + 3r = -4(-4 + r) 3 + 3r = (-4 * -4 + r * -4) 3 + 3r = (16 + -4r) Solving 3 + 3r = 16 + -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. 3 + 3r + 4r = 16 + -4r + 4r Combine like terms: 3r + 4r = 7r 3 + 7r = 16 + -4r + 4r Combine like terms: -4r + 4r = 0 3 + 7r = 16 + 0 3 + 7r = 16 Add '-3' to each side of the equation. 3 + -3 + 7r = 16 + -3 Combine like terms: 3 + -3 = 0 0 + 7r = 16 + -3 7r = 16 + -3 Combine like terms: 16 + -3 = 13 7r = 13 Divide each side by '7'. r = 1.857142857 Simplifying r = 1.857142857
