Simplifying 7x + 2 + 2x + 4 = 9x + 2 Reorder the terms: 2 + 4 + 7x + 2x = 9x + 2 Combine like terms: 2 + 4 = 6 6 + 7x + 2x = 9x + 2 Combine like terms: 7x + 2x = 9x 6 + 9x = 9x + 2 Reorder the terms: 6 + 9x = 2 + 9x Add '-9x' to each side of the equation. 6 + 9x + -9x = 2 + 9x + -9x Combine like terms: 9x + -9x = 0 6 + 0 = 2 + 9x + -9x 6 = 2 + 9x + -9x Combine like terms: 9x + -9x = 0 6 = 2 + 0 6 = 2 Solving 6 = 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.
