Simplifying (X + -3)(x + -4) = 12 Reorder the terms: (-3 + X)(x + -4) = 12 Reorder the terms: (-3 + X)(-4 + x) = 12 Multiply (-3 + X) * (-4 + x) (-3(-4 + x) + X(-4 + x)) = 12 ((-4 * -3 + x * -3) + X(-4 + x)) = 12 ((12 + -3x) + X(-4 + x)) = 12 (12 + -3x + (-4 * X + x * X)) = 12 (12 + -3x + (-4X + xX)) = 12 Reorder the terms: (12 + -4X + -3x + xX) = 12 (12 + -4X + -3x + xX) = 12 Add '-12' to each side of the equation. 12 + -4X + -3x + -12 + xX = 12 + -12 Reorder the terms: 12 + -12 + -4X + -3x + xX = 12 + -12 Combine like terms: 12 + -12 = 0 0 + -4X + -3x + xX = 12 + -12 -4X + -3x + xX = 12 + -12 Combine like terms: 12 + -12 = 0 -4X + -3x + xX = 0 Solving -4X + -3x + xX = 0 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. -4X + -3x + 3x + xX = 0 + 3x Combine like terms: -3x + 3x = 0 -4X + 0 + xX = 0 + 3x -4X + xX = 0 + 3x Remove the zero: -4X + xX = 3x Reorder the terms: -4X + -3x + xX = 3x + -3x Combine like terms: 3x + -3x = 0 -4X + -3x + xX = 0 The solution to this equation could not be determined.
