Simplifying -6 + 7(x + -1) = 14x + 4 + -7x Reorder the terms: -6 + 7(-1 + x) = 14x + 4 + -7x -6 + (-1 * 7 + x * 7) = 14x + 4 + -7x -6 + (-7 + 7x) = 14x + 4 + -7x Combine like terms: -6 + -7 = -13 -13 + 7x = 14x + 4 + -7x Reorder the terms: -13 + 7x = 4 + 14x + -7x Combine like terms: 14x + -7x = 7x -13 + 7x = 4 + 7x Add '-7x' to each side of the equation. -13 + 7x + -7x = 4 + 7x + -7x Combine like terms: 7x + -7x = 0 -13 + 0 = 4 + 7x + -7x -13 = 4 + 7x + -7x Combine like terms: 7x + -7x = 0 -13 = 4 + 0 -13 = 4 Solving -13 = 4 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.
