Simplifying 7(x + 2) + -3 = 2x + 5(2 + x) Reorder the terms: 7(2 + x) + -3 = 2x + 5(2 + x) (2 * 7 + x * 7) + -3 = 2x + 5(2 + x) (14 + 7x) + -3 = 2x + 5(2 + x) Reorder the terms: 14 + -3 + 7x = 2x + 5(2 + x) Combine like terms: 14 + -3 = 11 11 + 7x = 2x + 5(2 + x) 11 + 7x = 2x + (2 * 5 + x * 5) 11 + 7x = 2x + (10 + 5x) Reorder the terms: 11 + 7x = 10 + 2x + 5x Combine like terms: 2x + 5x = 7x 11 + 7x = 10 + 7x Add '-7x' to each side of the equation. 11 + 7x + -7x = 10 + 7x + -7x Combine like terms: 7x + -7x = 0 11 + 0 = 10 + 7x + -7x 11 = 10 + 7x + -7x Combine like terms: 7x + -7x = 0 11 = 10 + 0 11 = 10 Solving 11 = 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.
