Simplifying 6r + 2 = 2(r + 4) Reorder the terms: 2 + 6r = 2(r + 4) Reorder the terms: 2 + 6r = 2(4 + r) 2 + 6r = (4 * 2 + r * 2) 2 + 6r = (8 + 2r) Solving 2 + 6r = 8 + 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. 2 + 6r + -2r = 8 + 2r + -2r Combine like terms: 6r + -2r = 4r 2 + 4r = 8 + 2r + -2r Combine like terms: 2r + -2r = 0 2 + 4r = 8 + 0 2 + 4r = 8 Add '-2' to each side of the equation. 2 + -2 + 4r = 8 + -2 Combine like terms: 2 + -2 = 0 0 + 4r = 8 + -2 4r = 8 + -2 Combine like terms: 8 + -2 = 6 4r = 6 Divide each side by '4'. r = 1.5 Simplifying r = 1.5
