The answer would be 14x+5 I’m pretty sure
You surveyed 30 students to see how many CDs they owned.
The number of students who owned 5 - 8 CDs was:
= 15
The number of students who owned 9 - 12 CDs was:
= 10
The number of students who owned 13 - 16 CDs was:
= 5
The number of students who owned 17 - 20 CDs was:
= 0
The total number of students surveyed is the sum of the above:
= 15 + 10 + 5 + 0
= 30 students
30 students were surveyed for this study.

Since we have the 2.1 next to the parenthesis, we need to first distribute.
2.1 * x & 2.1 * 5
2.1x + 10.5
Then we take that and add the equals seven to the problem to move onto the next step.
2.1x + 10.5 = 7
We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.
2.1x + 10.5 = 7
- 10.5 -10.5
2.1x = -3.5
To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.
2.1x = -3.5
/2.1 /2.1
x = 1.66666666667
Hope this helped!
