Solution:
As we given that
then using this conversion factor we can write 
and further it can be written as

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
Answer:

Step-by-step explanation:

Let's solve the first equation for either x or y. I'll do it for x.

Begin by subtracting 5y.

Now divide by 5.

Simplify:

Now substitute x in the second equation for this value.

Distribute;

Add 6

Combine like terms;

Divide by -10.
