Take the value of each variable in the expression and replace the variable by its value. Then do the math!
You have to figure that out! Variables, in math, are there because you need to find them and figure the problem out. Usually, on the side it tells you what the variables mean, or you have to find that variable by making the equation make sense if they give u the answer.
An equation with a variable is a math problem with a missing number that you have to find out using some specific steps that you are taught. Example: 4+n=5. If you want to find out what the variable is, you have to do the OPPOSITE OPPERATION and find it out. So I would take the answer, and do the opposite operation and then the answer is the variable. Of course there are MUCH harder variable equations. :D
In math y or any other letter is known as a variable. Because to figure out the problem you must find out the value of y.
any number at all
