Simplifying 22 + -1(x + 9) = 7x + -3 Reorder the terms: 22 + -1(9 + x) = 7x + -3 22 + (9 * -1 + x * -1) = 7x + -3 22 + (-9 + -1x) = 7x + -3 Combine like terms: 22 + -9 = 13 13 + -1x = 7x + -3 Reorder the terms: 13 + -1x = -3 + 7x Solving 13 + -1x = -3 + 7x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7x' to each side of the equation. 13 + -1x + -7x = -3 + 7x + -7x Combine like terms: -1x + -7x = -8x 13 + -8x = -3 + 7x + -7x Combine like terms: 7x + -7x = 0 13 + -8x = -3 + 0 13 + -8x = -3 Add '-13' to each side of the equation. 13 + -13 + -8x = -3 + -13 Combine like terms: 13 + -13 = 0 0 + -8x = -3 + -13 -8x = -3 + -13 Combine like terms: -3 + -13 = -16 -8x = -16 Divide each side by '-8'. x = 2 Simplifying x = 2
