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.

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.
