Simplifying 3(x + -4) = 27 Reorder the terms: 3(-4 + x) = 27 (-4 * 3 + x * 3) = 27 (-12 + 3x) = 27 Solving -12 + 3x = 27 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + 3x = 27 + 12 Combine like terms: -12 + 12 = 0 0 + 3x = 27 + 12 3x = 27 + 12 Combine like terms: 27 + 12 = 39 3x = 39 Divide each side by '3'. x = 13 Simplifying x = 13
