Simplifying (X + 2)(2x + -1) = 9 Reorder the terms: (2 + X)(2x + -1) = 9 Reorder the terms: (2 + X)(-1 + 2x) = 9 Multiply (2 + X) * (-1 + 2x) (2(-1 + 2x) + X(-1 + 2x)) = 9 ((-1 * 2 + 2x * 2) + X(-1 + 2x)) = 9 ((-2 + 4x) + X(-1 + 2x)) = 9 (-2 + 4x + (-1 * X + 2x * X)) = 9 (-2 + 4x + (-1X + 2xX)) = 9 Reorder the terms: (-2 + -1X + 4x + 2xX) = 9 (-2 + -1X + 4x + 2xX) = 9 Solving -2 + -1X + 4x + 2xX = 9 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 + 4x + 2 + 2xX = 9 + 2 Reorder the terms: -2 + 2 + -1X + 4x + 2xX = 9 + 2 Combine like terms: -2 + 2 = 0 0 + -1X + 4x + 2xX = 9 + 2 -1X + 4x + 2xX = 9 + 2 Combine like terms: 9 + 2 = 11 -1X + 4x + 2xX = 11 Add '-4x' to each side of the equation. -1X + 4x + -4x + 2xX = 11 + -4x Combine like terms: 4x + -4x = 0 -1X + 0 + 2xX = 11 + -4x -1X + 2xX = 11 + -4x Reorder the terms: -11 + -1X + 4x + 2xX = 11 + -4x + -11 + 4x Reorder the terms: -11 + -1X + 4x + 2xX = 11 + -11 + -4x + 4x Combine like terms: 11 + -11 = 0 -11 + -1X + 4x + 2xX = 0 + -4x + 4x -11 + -1X + 4x + 2xX = -4x + 4x Combine like terms: -4x + 4x = 0 -11 + -1X + 4x + 2xX = 0 The solution to this equation could not be determined.
