Simplifying 4(x + 6) + 7 = 4x + 7 Reorder the terms: 4(6 + x) + 7 = 4x + 7 (6 * 4 + x * 4) + 7 = 4x + 7 (24 + 4x) + 7 = 4x + 7 Reorder the terms: 24 + 7 + 4x = 4x + 7 Combine like terms: 24 + 7 = 31 31 + 4x = 4x + 7 Reorder the terms: 31 + 4x = 7 + 4x Add '-4x' to each side of the equation. 31 + 4x + -4x = 7 + 4x + -4x Combine like terms: 4x + -4x = 0 31 + 0 = 7 + 4x + -4x 31 = 7 + 4x + -4x Combine like terms: 4x + -4x = 0 31 = 7 + 0 31 = 7 Solving 31 = 7 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.
