Simplifying 12x + 4 = 3(4x + -2) Reorder the terms: 4 + 12x = 3(4x + -2) Reorder the terms: 4 + 12x = 3(-2 + 4x) 4 + 12x = (-2 * 3 + 4x * 3) 4 + 12x = (-6 + 12x) Add '-12x' to each side of the equation. 4 + 12x + -12x = -6 + 12x + -12x Combine like terms: 12x + -12x = 0 4 + 0 = -6 + 12x + -12x 4 = -6 + 12x + -12x Combine like terms: 12x + -12x = 0 4 = -6 + 0 4 = -6 Solving 4 = -6 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.
