You can start by distributing the 5 to everything in the parenthesis.
5x-50=30-15x
Then get rid of your x values from one side, I chose to subtract 5x
-50 = 30 - 20x
Then subtract 30
-80=-20x
/-20
4=x
You can check by plugging your x into the equation to make sure it's right!

Answer:
72 cubic inches
Step-by-step explanation:
A volume of a box can be found using this equation: l x w x h
Length x Width x Height. We're given all 3 of the values, so multiply them together and voila, it's the volume of the given box!
8 x 3 x 3 = 72
1. You need to multiply the denominator by something that will make the content of the radical be a square—so that when you take the square root, you get something rational. Easiest and best is to multiply by √6. Of course, you must multiply the numerator by the same thing. Then simplify.
2. Identify the squares under the radical and remove them.
