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
