Simplifying (x + -3)(y + -4) = 1 Reorder the terms: (-3 + x)(y + -4) = 1 Reorder the terms: (-3 + x)(-4 + y) = 1 Multiply (-3 + x) * (-4 + y) (-3(-4 + y) + x(-4 + y)) = 1 ((-4 * -3 + y * -3) + x(-4 + y)) = 1 ((12 + -3y) + x(-4 + y)) = 1 (12 + -3y + (-4 * x + y * x)) = 1 (12 + -3y + (-4x + xy)) = 1 Reorder the terms: (12 + -4x + xy + -3y) = 1 (12 + -4x + xy + -3y) = 1 Solving 12 + -4x + xy + -3y = 1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -4x + xy + -12 + -3y = 1 + -12 Reorder the terms: 12 + -12 + -4x + xy + -3y = 1 + -12 Combine like terms: 12 + -12 = 0 0 + -4x + xy + -3y = 1 + -12 -4x + xy + -3y = 1 + -12 Combine like terms: 1 + -12 = -11 -4x + xy + -3y = -11 Add '3y' to each side of the equation. -4x + xy + -3y + 3y = -11 + 3y Combine like terms: -3y + 3y = 0 -4x + xy + 0 = -11 + 3y -4x + xy = -11 + 3y Reorder the terms: 11 + -4x + xy + -3y = -11 + 3y + 11 + -3y Reorder the terms: 11 + -4x + xy + -3y = -11 + 11 + 3y + -3y Combine like terms: -11 + 11 = 0 11 + -4x + xy + -3y = 0 + 3y + -3y 11 + -4x + xy + -3y = 3y + -3y Combine like terms: 3y + -3y = 0 11 + -4x + xy + -3y = 0 The solution to this equation could not be determined.
