Step-by-step explanation: To solve for <em>n</em> in the equation you see here, our goal is to get <em>n</em> by itself.
Our first step will be to isolate the term containing <em>n</em> 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 <em>n</em> by itself, since <em>n</em> 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.
