Simplifying -4n + 21 = 7(3 + n) Reorder the terms: 21 + -4n = 7(3 + n) 21 + -4n = (3 * 7 + n * 7) 21 + -4n = (21 + 7n) Add '-21' to each side of the equation. 21 + -21 + -4n = 21 + -21 + 7n Combine like terms: 21 + -21 = 0 0 + -4n = 21 + -21 + 7n -4n = 21 + -21 + 7n Combine like terms: 21 + -21 = 0 -4n = 0 + 7n -4n = 7n Solving -4n = 7n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-7n' to each side of the equation. -4n + -7n = 7n + -7n Combine like terms: -4n + -7n = -11n -11n = 7n + -7n Combine like terms: 7n + -7n = 0 -11n = 0 Divide each side by '-11'. n = 0 Simplifying n = 0
