Answer:
5
Step-by-step explanation:
We will use B for the number of baseball cards and H for the number of hockey cards.
B = 5H
B + H = 840
Use substitution by plugging 5H in for B in the second equation.
5H + H = 840
6H = 840
H = 140
If there are 140 hockey cards, then there are 5*140 = 700 baseball cards.
So the answer is 700.
