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
