Question

ax/b- by/a = a+b,
ax - by = 2ab.
by cross multiplication method.
any of write to try wrong question,i will report ​

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)

or, y=a

∴the required solution : x=-b, y=a
