Cheryl has some oranges. She puts the oranges into p boxes of 3 oranges each and has 2 oranges left. Find the total number of oranges Cheryl has in terms of p.

So 3 oranges per box and p boxes so

3 times p or 3p

then it didn't divide evenly so the remainder was 2

3p+2

this was the total

3p+2

We don't know how many oranges she has so we put x.

So, if she puts the oranges into p boxes of 3 oranges each and has 2 oranges left we can conclude this equation-

3p+2=x

So 3 times the number of boxes plus 2 equals how many oranges she has.
