4. A store had 86 DVDs and 52 CDs. When the equal number of DVDs and CDs were sold,
11Alexandr11 [23.1K]

Answer:

51 DVDs

Step-by-step explanation:

Let the number of DVDs and CDs sold be x each.

<u>Initial</u>

Number of DVDs= 86

Number of CDs= 52

<u>After selling</u>

Number of DVDs= 86 -x

Number of CDs= 52 -x

Given that there are 3 times as many DVDs than CDs left,

86 -x= 3(52 -x)

<em>Expand:</em>

86 -x= 156 -3x

<em>Bring x terms to 1 side, constant to the other:</em>

3x -x= 156 -86

<em>Simplify:</em>

2x= 70

<em>Divide both sides by 2:</em>

x= 35

Amount of DVDs left

= 86 -x

= 86 -35

= 51
