ax-by=2ab (2) by multiplication a a^2x-aby =2a^2b (4) by subtraction equations

-b^2y+aby =-a^2b+ab^2

y(-b^2+ab)=a^2b+ab^2

y= b(a^2+ab)/b(-b+a)

y =a^2+ab/a-b

putting the value of y in eqn (2)

ax-by =2ab

ax-b(a^2+ab)/a-b =2ab

ax=2ab+(a^2b-ab^2)/a-b

ax=2a^2b-2ab^2+a^2b-ab^2/a-b

ax=3a^2b-3ab^2/a-b

ax=3a(ab-b^2)a-b

x=3(ab-b^2)/a-b

ANSWER

x=3(ab-b^2)/a-b

y =a^2+ab/a-b
