5n (also known as 5xn)=10, which means n=2. n is the variable.

5-n=2 which means n=3

5/n (I'm trying to say 5 over n, also known as 5 divided by n)=20, which means n=0.25.

5+n=7 n=2.

If you are talking about math wise then an example of a variable would be any letter in the alphabet. For example in the expression "x-3m" m and x are variables.

The coefficient is the number to be multiplied by the unknown variable as for example 3x whereas 3 is the coefficient and x is the unknown variable.

You use variable in math problems to help you solve the answer. For example, you could do 50+50=a. The (a) would be the variable. Or for that same problem you could do 50+y=100. Then the (y) would be the variable.

its the number before the variable. example: 2x itd be 2

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

You consider both cases, then the variable is positive and when it is negative. For example, |x|
