use method of cross multiplication to solve the following system of linear equations.
$\frac{x}{a} + \frac{y}{b} = a + b \\ \frac{x}{ {a}^{2} } + \frac{y}{ {b}^{2} } = c$

Answer 1

May be this example will help u
b/a  - a/b
So x = {b^2 + a^2 / b} / {a^2 +b^2) / ab} = a
And y = ​{b^2 + a^2 / a} / {a^2 +b^2) / ab} = b
Solution; x = a and y = b
