Simplifying 5 + 7(x + -2) = 14x + 3 + -7x Reorder the terms: 5 + 7(-2 + x) = 14x + 3 + -7x 5 + (-2 * 7 + x * 7) = 14x + 3 + -7x 5 + (-14 + 7x) = 14x + 3 + -7x Combine like terms: 5 + -14 = -9 -9 + 7x = 14x + 3 + -7x Reorder the terms: -9 + 7x = 3 + 14x + -7x Combine like terms: 14x + -7x = 7x -9 + 7x = 3 + 7x Add '-7x' to each side of the equation. -9 + 7x + -7x = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 -9 + 0 = 3 + 7x + -7x -9 = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 -9 = 3 + 0 -9 = 3 Solving -9 = 3 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.
