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.
