Prime numbers are any number that is not divisible by a number. For example, 13 is a prime number because you can't divide anything into 13 and get a whole number.

When you replace a number with a letter, you assign a variable to the number.

Ex. x=10

20-x=10

20-10=10

10=10 so saying x=10 is true.
