SOLUTION: solve by cross multiplication method.. (a-b)x + (a+b)y = 2a^2 -2b^2 ax

SOLUTION: solve by cross multiplication method.. (a-b)x + (a+b)y = 2a^2 -2b^2 ax - by = a^2 + b^2

Question 750268: solve by cross multiplication method..
(a-b)x + (a+b)y = 2a^2 -2b^2
ax - by = a^2 + b^2

Equation with two unknown variables, maybe four unknown variables. No rational expression is present, so no cross-multiplication is practical. The equation would have infinite solutions. The best you could do is to put this seemingly linear, not quadratic, equation into a standard form.

... in which it IS already.

You could also put into slope intercept form:
