In order to solve equations like these, you need to move all terms involving the variable on one side, and all the numeric constants on the other side.
To do so, we can add/subtract the same quantity to both sides.
For example, we can add 5.2 to both sides to get

Then, we can add all the terms on the left hand side, and we have

Finally, we can divide both sides by -3.14:

In order to check the solution, we have to plug the value we found for x in the initial equation:

which is clearly true.

btw, don't put the shirts in the same bundle as the socks, you may end up with an unwanted perfume.
Well...this is a proportion problwm. for every 16 cups I have 1 gallon, so I can write that as:
16 cups
-----------
1 gallon
this value will be proportional to 1/4 a gallon equal "so many" cups. let's equal the unknown about of cups to x.
16 cups______ x cups
-----------.... = ..... ----------
1 gallon _____ 1/4 gallons
I can cross multiply to find x.
1 gallon • x cups = 16 cups • 1/4 gallons
16 times 1/4 is the same as 16/4, which equals 4.
1 gallon • x cups = 4 cups gallons
divide both sides by gallons
x cups = 4 cups
so! 1/4 of a gallon equals 4 cups.
