by cross multiplication
2ax+3by=(a+2b)
3ax+2by=(2a+b)
x/3b(2a+b)-2b(a+2b)=y/3a(a+2b)-2a(2a+b)=1/4ab-9ab
x/4ab-b^2=y/4ab-a^2=-5ab
x=b(4a-b)/-5ab=(b-4a)/a
y=a(4b-a)/-5ab=(a-4b)/b
2ax+3by=(a+2b)
3ax+2by=(2a+b)
x/3b(2a+b)-2b(a+2b)=y/3a(a+2b)-2a(2a+b)=1/4ab-9ab
x/4ab-b^2=y/4ab-a^2=-5ab
x=b(4a-b)/-5ab=(b-4a)/a
y=a(4b-a)/-5ab=(a-4b)/b
