Simplifying -3x + 4 = 3(4 + -1x) Reorder the terms: 4 + -3x = 3(4 + -1x) 4 + -3x = (4 * 3 + -1x * 3) 4 + -3x = (12 + -3x) Add '3x' to each side of the equation. 4 + -3x + 3x = 12 + -3x + 3x Combine like terms: -3x + 3x = 0 4 + 0 = 12 + -3x + 3x 4 = 12 + -3x + 3x Combine like terms: -3x + 3x = 0 4 = 12 + 0 4 = 12 Solving 4 = 12 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.
