Simplifying 3(x + 7) = 2(x + 9) + -1x Reorder the terms: 3(7 + x) = 2(x + 9) + -1x (7 * 3 + x * 3) = 2(x + 9) + -1x (21 + 3x) = 2(x + 9) + -1x Reorder the terms: 21 + 3x = 2(9 + x) + -1x 21 + 3x = (9 * 2 + x * 2) + -1x 21 + 3x = (18 + 2x) + -1x Combine like terms: 2x + -1x = 1x 21 + 3x = 18 + 1x Solving 21 + 3x = 18 + 1x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x' to each side of the equation. 21 + 3x + -1x = 18 + 1x + -1x Combine like terms: 3x + -1x = 2x 21 + 2x = 18 + 1x + -1x Combine like terms: 1x + -1x = 0 21 + 2x = 18 + 0 21 + 2x = 18 Add '-21' to each side of the equation. 21 + -21 + 2x = 18 + -21 Combine like terms: 21 + -21 = 0 0 + 2x = 18 + -21 2x = 18 + -21 Combine like terms: 18 + -21 = -3 2x = -3 Divide each side by '2'. x = -1.5 Simplifying x = -1.5
