Simplifying (X + -3)(x + -3) = 81 Reorder the terms: (-3 + X)(x + -3) = 81 Reorder the terms: (-3 + X)(-3 + x) = 81 Multiply (-3 + X) * (-3 + x) (-3(-3 + x) + X(-3 + x)) = 81 ((-3 * -3 + x * -3) + X(-3 + x)) = 81 ((9 + -3x) + X(-3 + x)) = 81 (9 + -3x + (-3 * X + x * X)) = 81 (9 + -3x + (-3X + xX)) = 81 Reorder the terms: (9 + -3X + -3x + xX) = 81 (9 + -3X + -3x + xX) = 81 Solving 9 + -3X + -3x + xX = 81 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -3X + -3x + -9 + xX = 81 + -9 Reorder the terms: 9 + -9 + -3X + -3x + xX = 81 + -9 Combine like terms: 9 + -9 = 0 0 + -3X + -3x + xX = 81 + -9 -3X + -3x + xX = 81 + -9 Combine like terms: 81 + -9 = 72 -3X + -3x + xX = 72 Add '3x' to each side of the equation. -3X + -3x + 3x + xX = 72 + 3x Combine like terms: -3x + 3x = 0 -3X + 0 + xX = 72 + 3x -3X + xX = 72 + 3x Reorder the terms: -72 + -3X + -3x + xX = 72 + 3x + -72 + -3x Reorder the terms: -72 + -3X + -3x + xX = 72 + -72 + 3x + -3x Combine like terms: 72 + -72 = 0 -72 + -3X + -3x + xX = 0 + 3x + -3x -72 + -3X + -3x + xX = 3x + -3x Combine like terms: 3x + -3x = 0 -72 + -3X + -3x + xX = 0 The solution to this equation could not be determined.
