Simplifying x + 7.5 = x + 6.5 Reorder the terms: 7.5 + x = x + 6.5 Reorder the terms: 7.5 + x = 6.5 + x Add '-1x' to each side of the equation. 7.5 + x + -1x = 6.5 + x + -1x Combine like terms: x + -1x = 0 7.5 + 0 = 6.5 + x + -1x 7.5 = 6.5 + x + -1x Combine like terms: x + -1x = 0 7.5 = 6.5 + 0 7.5 = 6.5 Solving 7.5 = 6.5 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.
