Add '2x' to each side of the equation. 10 + 1x + 2x = 2x + 2x Combine like terms: 1x + 2x = 1x 10 + 1x = 2x + 2x Combine like terms: 2x + 2x = 0 10 + 1x = 0 Add '10' to each side of the equation. 10 + 10 + 1x = 0 + 10 Combine like terms: 10 + 10 = 0 0 + 1x = 0 + 10 1x = 0 + 10 Combine like terms: 0 + 10 = 10 1x = 10 Divide each side by '1'. x = 10 Simplifying x = 10
