Question

Jason and Ron together have 97 baseball cards. Jason has four more than twice as many cards as ron. How many baseball cards does each person have?

Answer 1

set it up as equations.
jason has 4 MORE THAN TWICE as many as ron. we know more than means? and that twice means?

Answer 2

Let's say Jason has "x" amount of cards and Ron has "y" amount of cards.

Equation 1)
Together, they have 97 cards, so say:

x + y = 97

Equation 2)
Jason has 4 more than twice as many cards as Ron.

Jason's cards = (Twice Ron's cards) + 4

Twice Ron's cards is the same thing as "2y," so just put that and the symbol for Jason's cards into the equation
-->
x = (2y) + 4

So your two equations are:
1) x + y = 97
2) x = 2y + 4

One of the equations tell you what x is equal to, so just sub the second equation into the first.
Equation 1 changes from:
x + y = 97
-->
(2y + 4) + y = 97

Combine like terms and simplify to give you:
3y + 4 = 97

Subtract 4 from both sides then divide both sides by 3:
y = 31

So now we know Ron has 31.

We also know both their cards combined is 97, so just subtract 31 from 97 to find how many cards Jason has:
97 - 31 = ?
