Answer:
Step-by-step explanation: First you have to get the variable "n" by itself, because "n" is multiplied by "5" we then do the opposite of multiplication (which is divide), to get "n" by itself. We now divide 5n by 5, which gives us "n". Now.....what we do to the left side, we must also do the right side of the equation, so we also divide 20 by 5. And this gives us an answer of 4. Therefore, n = 4.
