Simplifying 6(x + 2) + 9 = 6x + 2 Reorder the terms: 6(2 + x) + 9 = 6x + 2 (2 * 6 + x * 6) + 9 = 6x + 2 (12 + 6x) + 9 = 6x + 2 Reorder the terms: 12 + 9 + 6x = 6x + 2 Combine like terms: 12 + 9 = 21 21 + 6x = 6x + 2 Reorder the terms: 21 + 6x = 2 + 6x Add '-6x' to each side of the equation. 21 + 6x + -6x = 2 + 6x + -6x Combine like terms: 6x + -6x = 0 21 + 0 = 2 + 6x + -6x 21 = 2 + 6x + -6x Combine like terms: 6x + -6x = 0 21 = 2 + 0 21 = 2 Solving 21 = 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.
