Simplifying (x + 9)(y + -2) = 0 Reorder the terms: (9 + x)(y + -2) = 0 Reorder the terms: (9 + x)(-2 + y) = 0 Multiply (9 + x) * (-2 + y) (9(-2 + y) + x(-2 + y)) = 0 ((-2 * 9 + y * 9) + x(-2 + y)) = 0 ((-18 + 9y) + x(-2 + y)) = 0 (-18 + 9y + (-2 * x + y * x)) = 0 (-18 + 9y + (-2x + xy)) = 0 Reorder the terms: (-18 + -2x + xy + 9y) = 0 (-18 + -2x + xy + 9y) = 0 Solving -18 + -2x + xy + 9y = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '18' to each side of the equation. -18 + -2x + xy + 18 + 9y = 0 + 18 Reorder the terms: -18 + 18 + -2x + xy + 9y = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -2x + xy + 9y = 0 + 18 -2x + xy + 9y = 0 + 18 Combine like terms: 0 + 18 = 18 -2x + xy + 9y = 18 Add '-9y' to each side of the equation. -2x + xy + 9y + -9y = 18 + -9y Combine like terms: 9y + -9y = 0 -2x + xy + 0 = 18 + -9y -2x + xy = 18 + -9y Reorder the terms: -18 + -2x + xy + 9y = 18 + -9y + -18 + 9y Reorder the terms: -18 + -2x + xy + 9y = 18 + -18 + -9y + 9y Combine like terms: 18 + -18 = 0 -18 + -2x + xy + 9y = 0 + -9y + 9y -18 + -2x + xy + 9y = -9y + 9y Combine like terms: -9y + 9y = 0 -18 + -2x + xy + 9y = 0 The solution to this equation could not be determined.
