Question

IF X-a, 4-bis the solution of the pair of
equalon X-9-2 and X:4 then wat
be value of a and b?​

Answer 1

Answer:

Substituting x = a & y = b in the given equation,

we get  

a - b  = 2 → (1)                

Adding equation (1) & (2) we get  

a + b =  1 → (2)    

⇒ 2a = 6      

⇒  a = 3

substituting a = 3 in (2)  we get b = 1
