Simplifying 2(r + 19) = 16 Reorder the terms: 2(19 + r) = 16 (19 * 2 + r * 2) = 16 (38 + 2r) = 16 Solving 38 + 2r = 16 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-38' to each side of the equation. 38 + -38 + 2r = 16 + -38 Combine like terms: 38 + -38 = 0 0 + 2r = 16 + -38 2r = 16 + -38 Combine like terms: 16 + -38 = -22 2r = -22 Divide each side by '2'. r = -11 Simplifying r = -11
