Step-by-step explanation:
Answer: The required value of y is 22.
Step-by-step explanation: We are given the following function of a and b :

We are to find the value of y when a = 1 and b = 2.
To find the required value of y, we need to substitute the values of a and b in equation (i).
From (i), we get

Thus, the required value of y is 22.
