Simplifying -7n + 7(4 + -8n) = 28 + -2n -7n + (4 * 7 + -8n * 7) = 28 + -2n -7n + (28 + -56n) = 28 + -2n Reorder the terms: 28 + -7n + -56n = 28 + -2n Combine like terms: -7n + -56n = -63n 28 + -63n = 28 + -2n Add '-28' to each side of the equation. 28 + -28 + -63n = 28 + -28 + -2n Combine like terms: 28 + -28 = 0 0 + -63n = 28 + -28 + -2n -63n = 28 + -28 + -2n Combine like terms: 28 + -28 = 0 -63n = 0 + -2n -63n = -2n Solving -63n = -2n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '2n' to each side of the equation. -63n + 2n = -2n + 2n Combine like terms: -63n + 2n = -61n -61n = -2n + 2n Combine like terms: -2n + 2n = 0 -61n = 0 Divide each side by '-61'. n = 0 Simplifying n = 0
