Solve this problem. What is n?

13+7+n=28

n=

Answer: n = 8

Step-by-step explanation: To solve this problem, we first combine our numbers which in this case are 13 and 7 which add to 20.

Now we have 20 + n = 28

To solve from here, we need to subtract 20 from the left side of the equation. Whatever we do to one side, we must also do to the other side so we will also subtract 20 from 28 and we get 8.

Now we have n = 8.

This means that n = 8.

n = 8

Step-by-step explanation:

13+7+n=28

n = 28 - 13 - 7

n = 8
