Asked by David

Bill has 12 more than three times the number of baseball cards Chyris has. Bill has 42 cards more than Chris. How many baseball cards does Chris have?

Answers

Answered by Henry
Chris = X cards
Bill = 3X + 12 cards.

X + (3X +12) = (X + 42) + X
4X - 2X = 42 - 12
2X = 30
X = 15 cards

Chris --x
Bill --- x+42

"Bill has 12 more than three times the number of baseball cards Chyris has" ---> x+42 = 3x + 12
