Question

solve by substitution method-

x/a + y/b = a+ b; x/a sq. + y/b square =2

Answer 1

Answer:

x=a2,y=b2

Step-by-step explanation:

Given that

xa+yb=a+b .........(1)  

xa2+yb2=2 .........(2)  

multiplying by b in (2) & subtracting from (1), we get

xa+yb−bxa2+byb2=a+b−2b  

(1a−ba2)x=a−b  

(a−ba2)x=a−b  

x=a2  

setting the value of  x  in (1), we get

a2a+yb=a+b  

a+yb=a+b  

yb=b  

y=b2  

hence, the solution of given linear equations is

x=a2,y=b2
