Weegy: Simplifying 4(x + 3) + -1(x + -2) = 0 Reorder the terms: 4(3 + x) + -1(x + -2) = 0 (3 * 4 + x * 4) + -1(x + -2) = 0 (12 + 4x) + -1(x + -2) = 0 Reorder the terms: 12 + 4x + -1(-2 + x) = 0 12 + 4x + (-2 * -1 + x * -1) = 0 12 + 4x + (2 + [ -1x) = 0 Reorder the terms: 12 + 2 + 4x + -1x = 0 Combine like terms: 12 + 2 = 14 14 + 4x + -1x = 0 Combine like terms: 4x + -1x = 3x 14 + 3x = 0 Solving 14 + 3x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + 3x = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 3x = 0 + -14 3x = 0 + -14 Combine like terms: 0 + -14 = -14 3x = -14 Divide each side by '3'. x = -4.666666667 Simplifying x = -4.666666667 ]
