Simplifying 6(7x + 2) = 42x + -9 Reorder the terms: 6(2 + 7x) = 42x + -9 (2 * 6 + 7x * 6) = 42x + -9 (12 + 42x) = 42x + -9 Reorder the terms: 12 + 42x = -9 + 42x Add '-42x' to each side of the equation. 12 + 42x + -42x = -9 + 42x + -42x Combine like terms: 42x + -42x = 0 12 + 0 = -9 + 42x + -42x 12 = -9 + 42x + -42x Combine like terms: 42x + -42x = 0 12 = -9 + 0 12 = -9 Solving 12 = -9 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.
