Simplifying (X + -2)(x + 1) = 1 Reorder the terms: (-2 + X)(x + 1) = 1 Reorder the terms: (-2 + X)(1 + x) = 1 Multiply (-2 + X) * (1 + x) (-2(1 + x) + X(1 + x)) = 1 ((1 * -2 + x * -2) + X(1 + x)) = 1 ((-2 + -2x) + X(1 + x)) = 1 (-2 + -2x + (1 * X + x * X)) = 1 (-2 + -2x + (1X + xX)) = 1 Reorder the terms: (-2 + 1X + -2x + xX) = 1 (-2 + 1X + -2x + xX) = 1 Solving -2 + 1X + -2x + xX = 1 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 1X + -2x + 2 + xX = 1 + 2 Reorder the terms: -2 + 2 + 1X + -2x + xX = 1 + 2 Combine like terms: -2 + 2 = 0 0 + 1X + -2x + xX = 1 + 2 1X + -2x + xX = 1 + 2 Combine like terms: 1 + 2 = 3 1X + -2x + xX = 3 Add '2x' to each side of the equation. 1X + -2x + 2x + xX = 3 + 2x Combine like terms: -2x + 2x = 0 1X + 0 + xX = 3 + 2x 1X + xX = 3 + 2x Reorder the terms: -3 + 1X + -2x + xX = 3 + 2x + -3 + -2x Reorder the terms: -3 + 1X + -2x + xX = 3 + -3 + 2x + -2x Combine like terms: 3 + -3 = 0 -3 + 1X + -2x + xX = 0 + 2x + -2x -3 + 1X + -2x + xX = 2x + -2x Combine like terms: 2x + -2x = 0 -3 + 1X + -2x + xX = 0 The solution to this equation could not be determined.
