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 Solving -12 + 4X + -3x + xX = 12 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 + 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 = 24 4X + -3x + xX = 24 Add '3x' to each side of the equation. 4X + -3x + 3x + xX = 24 + 3x Combine like terms: -3x + 3x = 0 4X + 0 + xX = 24 + 3x 4X + xX = 24 + 3x Reorder the terms: -24 + 4X + -3x + xX = 24 + 3x + -24 + -3x Reorder the terms: -24 + 4X + -3x + xX = 24 + -24 + 3x + -3x Combine like terms: 24 + -24 = 0 -24 + 4X + -3x + xX = 0 + 3x + -3x -24 + 4X + -3x + xX = 3x + -3x Combine like terms: 3x + -3x = 0 -24 + 4X + -3x + xX = 0 The solution to this equation could not be determined.
