Simplifying -30 + 12n = 3n + 3(3 + 3n) -30 + 12n = 3n + (3 * 3 + 3n * 3) -30 + 12n = 3n + (9 + 9n) Reorder the terms: -30 + 12n = 9 + 3n + 9n Combine like terms: 3n + 9n = 12n -30 + 12n = 9 + 12n Add '-12n' to each side of the equation. -30 + 12n + -12n = 9 + 12n + -12n Combine like terms: 12n + -12n = 0 -30 + 0 = 9 + 12n + -12n -30 = 9 + 12n + -12n Combine like terms: 12n + -12n = 0 -30 = 9 + 0 -30 = 9 Solving -30 = 9 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.
