Solution for x(y-b)=y(x-a) equation:


Simplifying
x(y + -1b) = y(x + -1a)

Reorder the terms:
x(-1b + y) = y(x + -1a)
(-1b * x + y * x) = y(x + -1a)
(-1bx + xy) = y(x + -1a)

Reorder the terms:
-1bx + xy = y(-1a + x)
-1bx + xy = (-1a * y + x * y)
-1bx + xy = (-1ay + xy)

Add '-1xy' to each side of the equation.
-1bx + xy + -1xy = -1ay + xy + -1xy

Combine like terms: xy + -1xy = 0
-1bx + 0 = -1ay + xy + -1xy
-1bx = -1ay + xy + -1xy

Combine like terms: xy + -1xy = 0
-1bx = -1ay + 0
-1bx = -1ay

Solving
-1bx = -1ay

Solving for variable 'b'.

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

Divide each side by '-1x'.
b = ax-1y

Simplifying
b = ax-1y
