Let the number of two dollar cards be x. The number of 5 dollar cards is also x.
Therefore
5x+2x = 252
7x = 252
x = 36

The total value of a pair consisting of $5 card and $2 card is 7.
If the total value is 252, then Frank has $252/$7= 36 such pairs.
So he has 36 of each of the $5 and $2 cards.

Let x = the number of 5 dollar cards, and the number of 2 dollar cards.
5x+2x=252 (the value in dollars)
7x=252
x=36
He has 36 of each.

Make it into an equation with x being the number of cards of each value.
5x+2x=252
7x=252
x=252/7
x=36

Let number of $2 cards = X
Therefore, number of $5 cards = X (Given)
5X = value of $5 cards
2X = value of $2 cards
5X + 2X = 252
7X = 252
X = 36
Therefore, 36 of each.
