Heidi donations = x
Grandpa = x - 2
Heidi + Grandpa = Total donations

x + (x-2) = 7

Jose had 4 times as many trading cards as Philippe. After Jose gave away 50 cards to his little brother and Philippe gave 5 card
tensa zangetsu [6.8K]

Answer:

Jose had 60 cards

Phillipe had 15 cards

Step-by-step explanation:

Let the number of trading cards Phillipe had be x. Jose had 4 times, meaning he has 4x of these cards.

Jose gave away 50 cards while Phillipe gave away 5 cards to make their numbers equal.

Mathematically:

4x - 50 = x - 5

3x = 45

x = 45/3 = 15

Phillipe had 15 cards while Jose had 15(4) = 60 cards
