Question

ax /b_by/ a=a+ b,ax_by=2ab then x = ​

Answer 1

ax/b - by/a=a+b -------------(1)

ax - by=2ab ------------------(2)

 Using cross multiplication method we get,

 x/(2b²-ab-b²)=y/(-a²-ab+2a²)=1/(a-b)

or, x/(b²-ab)=y/(a²-ab)=1/(a-b)

or, x/(-b)(a-b)=y/a(a-b)=1/(a-b)

Equating the first and the last part,

x/(-b)(a-b)=1/(a-b)

or, x=(-b)(a-b)/(a-b)

or, x=-b

Again equating the last two parts,

y/a(a-b)=1/(a-b)

or, y=a(a-b)/(a-b)
