Distribute on the left
3x-15=7x
Subtract 3x from both sides
-15= 4x
Divide both sides by 4
-15/4= x
Final answer: x=-15/4 or -3.75
The answer is 28
bc 3+(5x5) = 3+25 and 3+25 is 28

Step-by-step explanation:
DVDs comprises 31.3% of total. And we also know that there are 308 DVD. Thus, we can say:
308 is 31.3% of total
We can let total be x, thus we can write an equation as:
308 = 0.313x
Solving for x:
![308 = 0.313x\\x=\frac{308}{0.313}\\x=984.02](https://tex.z-dn.net/?f=308%20%3D%200.313x%5C%5Cx%3D%5Cfrac%7B308%7D%7B0.313%7D%5C%5Cx%3D984.02)
We can round and say there are 984 total movies
