To solve this equation, we need to get the variable n alone on the right side of the equation. To do this, we need to get rid of the denominator on this variable. To get rid of the denominator, we must multiply both sides by 2, because multiplication is the inverse operation of division (which is being used to create the denominator).
-5 = n/2
-5 * 2 = n/2 * 2
-10 = n
Therefore, your answer is that n = -10.
If you ever want to check and make sure your answer is correct, you can plug this value back into the original equation. -5 = -10/2, which is a true statement, so we know our answer is correct.
Hope this helps!
