Simplifying -2 = 2(2n + 1) Reorder the terms: -2 = 2(1 + 2n) -2 = (1 * 2 + 2n * 2) -2 = (2 + 4n) Solving -2 = 2 + 4n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4n' to each side of the equation. -2 + -4n = 2 + 4n + -4n Combine like terms: 4n + -4n = 0 -2 + -4n = 2 + 0 -2 + -4n = 2 Add '2' to each side of the equation. -2 + 2 + -4n = 2 + 2 Combine like terms: -2 + 2 = 0 0 + -4n = 2 + 2 -4n = 2 + 2 Combine like terms: 2 + 2 = 4 -4n = 4 Divide each side by '-4'. n = -1 Simplifying n = -1
