Simplifying 2x + -3x + -3 = 7 + -1x + -1 Reorder the terms: -3 + 2x + -3x = 7 + -1x + -1 Combine like terms: 2x + -3x = -1x -3 + -1x = 7 + -1x + -1 Reorder the terms: -3 + -1x = 7 + -1 + -1x Combine like terms: 7 + -1 = 6 -3 + -1x = 6 + -1x Add 'x' to each side of the equation. -3 + -1x + x = 6 + -1x + x Combine like terms: -1x + x = 0 -3 + 0 = 6 + -1x + x -3 = 6 + -1x + x Combine like terms: -1x + x = 0 -3 = 6 + 0 -3 = 6 Solving -3 = 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.
