Answer:
The company produced 27 motorcycle tires that week.

I am going to say that:
x is the number of car tyres produced that week.
y is the number of motorcycle tyres produced that week.
70 vehicles:
This means that

269 tires:
A car has four tyres, and an extra spare tyre is produced. So for each car, 5 tyres.
A motorcycle has two tyres. No spares are produced. So

We want to find y.
From the first equation:

Replacing in the second





The company produced 27 motorcycle tires that week.
