Simplifying 7x + 4 = 7(x + -2) Reorder the terms: 4 + 7x = 7(x + -2) Reorder the terms: 4 + 7x = 7(-2 + x) 4 + 7x = (-2 * 7 + x * 7) 4 + 7x = (-14 + 7x) Add '-7x' to each side of the equation. 4 + 7x + -7x = -14 + 7x + -7x Combine like terms: 7x + -7x = 0 4 + 0 = -14 + 7x + -7x 4 = -14 + 7x + -7x Combine like terms: 7x + -7x = 0 4 = -14 + 0 4 = -14 Solving 4 = -14 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.
