Simplifying (X + 2)(x + -4) = 55 Reorder the terms: (2 + X)(x + -4) = 55 Reorder the terms: (2 + X)(-4 + x) = 55 Multiply (2 + X) * (-4 + x) (2(-4 + x) + X(-4 + x)) = 55 ((-4 * 2 + x * 2) + X(-4 + x)) = 55 ((-8 + 2x) + X(-4 + x)) = 55 (-8 + 2x + (-4 * X + x * X)) = 55 (-8 + 2x + (-4X + xX)) = 55 Reorder the terms: (-8 + -4X + 2x + xX) = 55 (-8 + -4X + 2x + xX) = 55 Solving -8 + -4X + 2x + xX = 55 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '8' to each side of the equation. -8 + -4X + 2x + 8 + xX = 55 + 8 Reorder the terms: -8 + 8 + -4X + 2x + xX = 55 + 8 Combine like terms: -8 + 8 = 0 0 + -4X + 2x + xX = 55 + 8 -4X + 2x + xX = 55 + 8 Combine like terms: 55 + 8 = 63 -4X + 2x + xX = 63 Add '-2x' to each side of the equation. -4X + 2x + -2x + xX = 63 + -2x Combine like terms: 2x + -2x = 0 -4X + 0 + xX = 63 + -2x -4X + xX = 63 + -2x Reorder the terms: -63 + -4X + 2x + xX = 63 + -2x + -63 + 2x Reorder the terms: -63 + -4X + 2x + xX = 63 + -63 + -2x + 2x Combine like terms: 63 + -63 = 0 -63 + -4X + 2x + xX = 0 + -2x + 2x -63 + -4X + 2x + xX = -2x + 2x Combine like terms: -2x + 2x = 0 -63 + -4X + 2x + xX = 0 The solution to this equation could not be determined.
