Solution for x*y=(x-12)(y-12)+12 equation:


Simplifying
x * y = (x + -12)(y + -12) + 12

Multiply x * y
xy = (x + -12)(y + -12) + 12

Reorder the terms:
xy = (-12 + x)(y + -12) + 12

Reorder the terms:
xy = (-12 + x)(-12 + y) + 12

Multiply (-12 + x) * (-12 + y)
xy = (-12(-12 + y) + x(-12 + y)) + 12
xy = ((-12 * -12 + y * -12) + x(-12 + y)) + 12
xy = ((144 + -12y) + x(-12 + y)) + 12
xy = (144 + -12y + (-12 * x + y * x)) + 12
xy = (144 + -12y + (-12x + xy)) + 12

Reorder the terms:
xy = (144 + -12x + xy + -12y) + 12
xy = (144 + -12x + xy + -12y) + 12

Reorder the terms:
xy = 144 + 12 + -12x + xy + -12y

Combine like terms: 144 + 12 = 156
xy = 156 + -12x + xy + -12y

Add '-1xy' to each side of the equation.
xy + -1xy = 156 + -12x + xy + -1xy + -12y

Combine like terms: xy + -1xy = 0
0 = 156 + -12x + xy + -1xy + -12y

Combine like terms: xy + -1xy = 0
0 = 156 + -12x + 0 + -12y
0 = 156 + -12x + -12y

Solving
0 = 156 + -12x + -12y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12x' to each side of the equation.
0 + 12x = 156 + -12x + 12x + -12y
Remove the zero:
12x = 156 + -12x + 12x + -12y

Combine like terms: -12x + 12x = 0
12x = 156 + 0 + -12y
12x = 156 + -12y

Divide each side by '12'.
x = 13 + -1y

Simplifying
x = 13 + -1y
