Simplifying 7(x + 2) + 5 = 7x + 2 Reorder the terms: 7(2 + x) + 5 = 7x + 2 (2 * 7 + x * 7) + 5 = 7x + 2 (14 + 7x) + 5 = 7x + 2 Reorder the terms: 14 + 5 + 7x = 7x + 2 Combine like terms: 14 + 5 = 19 19 + 7x = 7x + 2 Reorder the terms: 19 + 7x = 2 + 7x Add '-7x' to each side of the equation. 19 + 7x + -7x = 2 + 7x + -7x Combine like terms: 7x + -7x = 0 19 + 0 = 2 + 7x + -7x 19 = 2 + 7x + -7x Combine like terms: 7x + -7x = 0 19 = 2 + 0 19 = 2 Solving 19 = 2 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.
