solve the problems. help me​

Answer 1

Answer:

Option (b)a,b is correct.

Explanation:

ax + by =2ab ..(1)

bx + ay = a²+b² ...(2)

multiply by b in (1) and a in (2)

we get ,

abx+b²y=2ab²

abx+a²y=a³+ab²

subtract (1)-(2),

Y(-a²+b²)=2ab²-a³-ab²

y(-a²+b²)=ab²-a³

y= (ab²-a³)/(-a²+b²)

y= a(b²-a²)/(b²-a²)

y=a

put value in (1),

ax+b[a]=2ab

ax=2ab-ab

ax= ab

x=ba/a

x=b
