Together Ron and Tori have 35 trading cards. Ron has 9 more than Tori. How many cards does Ron have?

Ron has 22 cards

number one tip in math, try to create equation!

set number of cards Ron has as x (always set x as what you are looking for)

set number of cards Tori has as (x-9) because if Ron has 9 more cards than Tori that's same thing as saying Tori has 9 cards less than Ron

Number of cards Tori and Ron has need to equal 35

Therefore,

x + (x-9) = 35

Solve:

2x-9=35

bring over 9 to other side

2x=44

divide both sides by 2

x=22

So number of cards Ron has is 22
