Question

A bowl contains a total of 26 blue and red marbles. There are two more red marbles than

blue marbles. How many blue marbles are in the bowl?
Which of the following let statements should you use?

Let x = the number of red marbles. Let x + 2 = the number

of blue marbles.
Let x = the number of blue marbles. Let 2x = the number of
red marbles.

Let x = the number of blue marbles. Let x + 2 = the number
of red marbles.

Answer 1

marbles. So there are x+2 red marbles. If you add them together you

get x + x + 2....and all that equals 26 (subtract 2 from each side
