3n-5 equals 7 n equals

Answer 1

Let's write the question out.

3n - 5 = 7

First,we'll move the 5 to the other side by adding 5 to both sides. Adding 5 to the left will cancel out the '-5' on the left side.

3n = 7 + 5

3n = 12

Now, we'll divide both sides by 3. That will leave the left side as '1n' since 3/3=1

n = 12/3

n = 4
