Simplifying -3n + -4 = -3n + 1 Reorder the terms: -4 + -3n = -3n + 1 Reorder the terms: -4 + -3n = 1 + -3n Add '3n' to each side of the equation. -4 + -3n + 3n = 1 + -3n + 3n Combine like terms: -3n + 3n = 0 -4 + 0 = 1 + -3n + 3n -4 = 1 + -3n + 3n Combine like terms: -3n + 3n = 0 -4 = 1 + 0 -4 = 1 Solving -4 = 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.
