Solve by cross multiplication (a+b)x+(a-b)y =2ab and( a-b)x+(a+b )y=a^

1.	Solve by cross multiplication (a+b)x+(a-b)y =2ab and( a-b)x+(a+b )y=a^2+b ^2
Answer» x = a + b{tex}\\therefore{/tex} (a - b)(a + b) + (a + b)y = a2 - b2 - 2aba2 - b2 + (a + b)y = a2 - b2 - 2ab{tex}y = \\frac{{ - 2ab}}{{a + b}}{/tex}
