Jack has three more cards than Bill. Together they have 47 cards. If x represents the number of cards Bill has, then an equation that can be used to determine the number of cards each one has is

x + 3 = 47

2x + 3 = 47

x - 3 = 47

2x - 3 = 47

3x + 3 = 47

Correct Answer : 2x + 3 = 47. Choice (2)

Explanatory Answer

Bill has x cards.

Jack has 3 more cards than Bill. So, Jack has x + 3 cards.

So, together Bill and Jack have x + x + 3 = 2x + 3 cards.

The question states that they have 47 cards between them.
