Simplifying 2x + 5 = 2(x + -3) + -9 Reorder the terms: 5 + 2x = 2(x + -3) + -9 Reorder the terms: 5 + 2x = 2(-3 + x) + -9 5 + 2x = (-3 * 2 + x * 2) + -9 5 + 2x = (-6 + 2x) + -9 Reorder the terms: 5 + 2x = -6 + -9 + 2x Combine like terms: -6 + -9 = -15 5 + 2x = -15 + 2x Add '-2x' to each side of the equation. 5 + 2x + -2x = -15 + 2x + -2x Combine like terms: 2x + -2x = 0 5 + 0 = -15 + 2x + -2x 5 = -15 + 2x + -2x Combine like terms: 2x + -2x = 0 5 = -15 + 0 5 = -15 Solving 5 = -15 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.
