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