Question
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
Henry
Chris = X cards
Bill = 3X + 12 cards.
X + (3X +12) = (X + 42) + X
4X - 2X = 42 - 12
2X = 30
X = 15 cards
Bill = 3X + 12 cards.
X + (3X +12) = (X + 42) + X
4X - 2X = 42 - 12
2X = 30
X = 15 cards
Reiny
Chris --x
Bill --- x+42
"Bill has 12 more than three times the number of baseball cards Chyris has" ---> x+42 = 3x + 12
solve
Bill --- x+42
"Bill has 12 more than three times the number of baseball cards Chyris has" ---> x+42 = 3x + 12
