Answer: n = 4

Step-by-step explanation:

The given expression is

2n+4=12

We want to solve for n. The first step is to make 2n stand alone on the left hand side of the equation. This is achieved by subtracting 4 from the left hand side and the right hand side of the equation. It becomes

2n + 4 - 4=12 - 4

2n = 8

The next step is to divide the left hand side and the right hand side of the equation by 2. It becomes

2n/2 = 8/2

n = 4
