Simplifying 9(x + -2) = 3(x + 7) Reorder the terms: 9(-2 + x) = 3(x + 7) (-2 * 9 + x * 9) = 3(x + 7) (-18 + 9x) = 3(x + 7) Reorder the terms: -18 + 9x = 3(7 + x) -18 + 9x = (7 * 3 + x * 3) -18 + 9x = (21 + 3x) Solving -18 + 9x = 21 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -18 + 9x + -3x = 21 + 3x + -3x Combine like terms: 9x + -3x = 6x -18 + 6x = 21 + 3x + -3x Combine like terms: 3x + -3x = 0 -18 + 6x = 21 + 0 -18 + 6x = 21 Add '18' to each side of the equation. -18 + 18 + 6x = 21 + 18 Combine like terms: -18 + 18 = 0 0 + 6x = 21 + 18 6x = 21 + 18 Combine like terms: 21 + 18 = 39 6x = 39 Divide each side by '6'. x = 6.5 Simplifying x = 6.5
