This is a very common type of problem.
Let A be the number of apples and O be the number of oranges.
You are told
we are using cents here instead of dollars

You have two equations and two unknowns. So you can solve this one
Now you can use your favorite method to solve.
Let's use substitution

Now use that and plug it into the second equation as follows

so an apple is 20 cents
If an apple it 20 then plug in to find the cost of an orange

oranges are a dime. Go not sure what store you shop at, but fruit is a steal :)
Check you answer using the second equation. Does
???
