ax/b-by/a=a+b (1) by LCM a^2x-b^2y =a^2b+ab^2 (3)
\n" ); document.write( "ax-by=2ab (2) by multiplication a a^2x-aby =2a^2b (4) by subtraction equations
\n" ); document.write( "-b^2y+aby =-a^2b+ab^2
\n" ); document.write( "y(-b^2+ab)=a^2b+ab^2
\n" ); document.write( "y= b(a^2+ab)/b(-b+a)
\n" ); document.write( "y =a^2+ab/a-b
\n" ); document.write( "putting the value of y in eqn (2)\r
