Question

and Bill collect coins. Karen has x coins. Bill has 6 coins fewer than two times the number of coins Karen has. Write and simplify an expression for the total number of coins Karen and Bill have.

Answer 1

Answer: the total amount of coins Bill and Karen have can be found with the following equation: 3x-6

Explanation:

Karen has x coins

Bill's coins are twice the x, so 2x, and he has 6 fewer than that.

The equation becomes x+2x-6 which can be simplified to 3x-6.

Answer 2

3x - 6

Explanation:

Let's call the number of coins Karen has "x".

According to the information given, Bill has 6 coins fewer than two times the number of coins Karen has, so we can write the following expression for the number of coins Bill has:

Bill: 2x - 6

To find the total number of coins Karen and Bill have, we simply add the number of coins each person has:

Karen + Bill: x + (2x - 6) = 3x - 6

So the total number of coins Karen and Bill have is 3x - 6.
