Simplifying 4x + -9 = 4(x + 2) Reorder the terms: -9 + 4x = 4(x + 2) Reorder the terms: -9 + 4x = 4(2 + x) -9 + 4x = (2 * 4 + x * 4) -9 + 4x = (8 + 4x) Add '-4x' to each side of the equation. -9 + 4x + -4x = 8 + 4x + -4x Combine like terms: 4x + -4x = 0 -9 + 0 = 8 + 4x + -4x -9 = 8 + 4x + -4x Combine like terms: 4x + -4x = 0 -9 = 8 + 0 -9 = 8 Solving -9 = 8 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.
