Simplifying 7(x + -5) + 5 = 7x + 3 Reorder the terms: 7(-5 + x) + 5 = 7x + 3 (-5 * 7 + x * 7) + 5 = 7x + 3 (-35 + 7x) + 5 = 7x + 3 Reorder the terms: -35 + 5 + 7x = 7x + 3 Combine like terms: -35 + 5 = -30 -30 + 7x = 7x + 3 Reorder the terms: -30 + 7x = 3 + 7x Add '-7x' to each side of the equation. -30 + 7x + -7x = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 -30 + 0 = 3 + 7x + -7x -30 = 3 + 7x + -7x Combine like terms: 7x + -7x = 0 -30 = 3 + 0 -30 = 3 Solving -30 = 3 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.
