Final answer:
To solve the equation N/10 - 20 = 0, add 20 to both sides and multiply both sides by 10 to get N = 200.
Step-by-step explanation:
To solve the equation N/10 - 20 = 0, we want to isolate the variable N.
First, add 20 to both sides of the equation to get N/10 = 20.
Then, multiply both sides of the equation by 10 to get N = 200.
