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