Answer 1

The number of CDs in Walter's collection, represented by x, is 36.

Step-by-step explanation:

Let's represent the number of CDs in Walter's collection as x.

According to the question, the number of CDs in Brian's collection is 3 times the number in Walter's collection, so the number of CDs in Brian's collection can be represented as 3x.

The total number of CDs in both collections is given as 144.

Therefore, the equation representing the total number of CDs is:

x + 3x = 144.

Simplifying this equation, we get:

4x = 144.

Dividing both sides by 4, we find that x = 36.

So, the number of CDs in Walter's collection, represented as x, is 36.
