Simplifying 6x + -4 = 6(x + -7) Reorder the terms: -4 + 6x = 6(x + -7) Reorder the terms: -4 + 6x = 6(-7 + x) -4 + 6x = (-7 * 6 + x * 6) -4 + 6x = (-42 + 6x) Add '-6x' to each side of the equation. -4 + 6x + -6x = -42 + 6x + -6x Combine like terms: 6x + -6x = 0 -4 + 0 = -42 + 6x + -6x -4 = -42 + 6x + -6x Combine like terms: 6x + -6x = 0 -4 = -42 + 0 -4 = -42 Solving -4 = -42 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.
