Simplifying 12n + 13 = 6(2n + 6) Reorder the terms: 13 + 12n = 6(2n + 6) Reorder the terms: 13 + 12n = 6(6 + 2n) 13 + 12n = (6 * 6 + 2n * 6) 13 + 12n = (36 + 12n) Add '-12n' to each side of the equation. 13 + 12n + -12n = 36 + 12n + -12n Combine like terms: 12n + -12n = 0 13 + 0 = 36 + 12n + -12n 13 = 36 + 12n + -12n Combine like terms: 12n + -12n = 0 13 = 36 + 0 13 = 36 Solving 13 = 36 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.
