Answer: n = 8

Step-by-step explanation: To solve for n in the equation you see here, our goal is to get n by itself.

Our first step will be to isolate the term containing n which in this case is 5n. To isolate 5n, we have to get rid of the +5 by subtracting 5 from both sides od the equation. On the left, the 5's cancel each other out and we're left with 5n. On the right, 45 - 5 simplifies to 40.

Now we have 5n = 40 which is a one-step equation.

To get n by itself, since n is being multiplied by 5, we divide by 5 on the left and on the right side of the equation. On the left side, the 5's cancel each other out and on the right side, 40 over 5 simplifies to 8.

Now we have n = 8.

Answer:

n=8

Explanation:

First you subtract 5 from the left side to get 40, then you divide 5 by 40 to get 8. When doing equations you always do the opposite of what it says
