Answer:
n = 4
Explanation:
Pre-Solving
We are given the equation 7n - 2 = 5n + 6, ans we want to solve it for n. 
To do this, we need to isolate n one one side. 
Solving
Let's start by adding 2 to both sides. 
7n - 2 = 5n + 6 
 +2 +2
_______________
7n = 5n + 8
Now, subtract 5n from both sides. 
7n = 5n + 8
-5n -5n
_______________
2n = 8 
Divide both sides by 8 to get the value of n. 
2n = 8 
÷2 ÷2
________
n = 4
