Putting x = 1
=> 
Given that f(1) = 1
=> 
=>
-------------------(1)
Now,
Putting x = 2
=> 
Given that f(2) = 5
=> 
=> 
=>
----------------(2)
Subtracting (2) from (1)

For b , Put a = 9 in equation (1)

If
and
, then you can replace
in either equation with the equivalent expression given by the other equation. In this case, you have

and you can solve for
.

Then
.
For the second system, you can write


Then substitute this into the second equation and you get


so that
