<span>Simplifying 6(2x + -11) + 15 = 21        Reorder the terms: 6(-11 + 2x) + 15 = 21 (-11 * 6 + 2x * 6) + 15 = 21 (-66 + 12x) + 15 = 21         Reorder the terms: -66 + 15 + 12x = 21       Combine like terms: -66 + 15 = -51 -51 + 12x = 21     Solving -51 + 12x = 21 Solving for variable 'x'.          Move all terms containing x to the left, all other terms to the right. Add '51' to each side of the equation. -51 + 51 + 12x = 21 + 51 Combine like terms: -51 + 51 = 0 0 + 12x = 21 + 51 12x = 21 + 51       Combine like terms: 21 + 51 = 72 12x = 72 Divide each side by '12'. x = 6 Simplifying x = 6</span>
