Simplifying 7(x + 1) + 4 = 3x + 4(2 + x) Reorder the terms: 7(1 + x) + 4 = 3x + 4(2 + x) (1 * 7 + x * 7) + 4 = 3x + 4(2 + x) (7 + 7x) + 4 = 3x + 4(2 + x) Reorder the terms: 7 + 4 + 7x = 3x + 4(2 + x) Combine like terms: 7 + 4 = 11 11 + 7x = 3x + 4(2 + x) 11 + 7x = 3x + (2 * 4 + x * 4) 11 + 7x = 3x + (8 + 4x) Reorder the terms: 11 + 7x = 8 + 3x + 4x Combine like terms: 3x + 4x = 7x 11 + 7x = 8 + 7x Add '-7x' to each side of the equation. 11 + 7x + -7x = 8 + 7x + -7x Combine like terms: 7x + -7x = 0 11 + 0 = 8 + 7x + -7x 11 = 8 + 7x + -7x Combine like terms: 7x + -7x = 0 11 = 8 + 0 11 = 8 Solving 11 = 8 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.
