Simplifying 15 = 4.3n + -2.1(n + -4) Reorder the terms: 15 = 4.3n + -2.1(-4 + n) 15 = 4.3n + (-4 * -2.1 + n * -2.1) 15 = 4.3n + (8.4 + -2.1n) Reorder the terms: 15 = 8.4 + 4.3n + -2.1n Combine like terms: 4.3n + -2.1n = 2.2n 15 = 8.4 + 2.2n Solving 15 = 8.4 + 2.2n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2.2n' to each side of the equation. 15 + -2.2n = 8.4 + 2.2n + -2.2n Combine like terms: 2.2n + -2.2n = 0.0 15 + -2.2n = 8.4 + 0.0 15 + -2.2n = 8.4 Add '-15' to each side of the equation. 15 + -15 + -2.2n = 8.4 + -15 Combine like terms: 15 + -15 = 0 0 + -2.2n = 8.4 + -15 -2.2n = 8.4 + -15 Combine like terms: 8.4 + -15 = -6.6 -2.2n = -6.6 Divide each side by '-2.2'. n = 3 Simplifying n = 3
