Simplifying 3n + 7 = 7(n + -9) + -4n Reorder the terms: 7 + 3n = 7(n + -9) + -4n Reorder the terms: 7 + 3n = 7(-9 + n) + -4n 7 + 3n = (-9 * 7 + n * 7) + -4n 7 + 3n = (-63 + 7n) + -4n Combine like terms: 7n + -4n = 3n 7 + 3n = -63 + 3n Add '-3n' to each side of the equation. 7 + 3n + -3n = -63 + 3n + -3n Combine like terms: 3n + -3n = 0 7 + 0 = -63 + 3n + -3n 7 = -63 + 3n + -3n Combine like terms: 3n + -3n = 0 7 = -63 + 0 7 = -63 Solving 7 = -63 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.
