The video tutorial explains how to solve a word problem involving CDs. Dave has 16 more CDs than Brianna, and together they have 82 CDs. The teacher guides through understanding the problem, choosing a variable to represent the unknowns, setting up an equation, and solving it to find that Brianna has 33 CDs and Dave has 49 CDs.

What is the total number of CDs that Dave and Brianna have together?

• 82

• 33

• 49

• 66

Why is it beneficial to use a single variable to represent Brianna's CDs?

• It makes the problem more complex.

• It is a requirement for all math problems.

• It simplifies the problem by reducing the number of unknowns.

• It allows for more variables to be used.

If Brianna has X CDs, how many CDs does Dave have?

• X - 16

• 2X

• X + 16

• X

What is the value of X, representing Brianna's CDs, after solving the equation?

• 82

• 16

• 33

• 49

How many CDs does Dave have after solving the problem?
