Quinn Stephenson · Answer 1

Keith started with (prior to the 7 new cards) 67 baseball cards. However, if we're also counting the new ones, then 74 cards.

Step-by-step explanation:

37*2=74

or x+7/2=37

x+7=74

-7 on both sides

x=67

Mollie · Answer 2

67

Step-by-step explanation:

(X+7) / 2 = 37

X = 67
