Simplifying 5n + -2(n + 2) = 8 Reorder the terms: 5n + -2(2 + n) = 8 5n + (2 * -2 + n * -2) = 8 5n + (-4 + -2n) = 8 Reorder the terms: -4 + 5n + -2n = 8 Combine like terms: 5n + -2n = 3n -4 + 3n = 8 Solving -4 + 3n = 8 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + 3n = 8 + 4 Combine like terms: -4 + 4 = 0 0 + 3n = 8 + 4 3n = 8 + 4 Combine like terms: 8 + 4 = 12 3n = 12 Divide each side by '3'. n = 4 Simplifying n = 4
