Simplifying 18 + 2x = 2(x + 5) Reorder the terms: 18 + 2x = 2(5 + x) 18 + 2x = (5 * 2 + x * 2) 18 + 2x = (10 + 2x) Add '-2x' to each side of the equation. 18 + 2x + -2x = 10 + 2x + -2x Combine like terms: 2x + -2x = 0 18 + 0 = 10 + 2x + -2x 18 = 10 + 2x + -2x Combine like terms: 2x + -2x = 0 18 = 10 + 0 18 = 10 Solving 18 = 10 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
