4

Step-by-step explanation:

Simplifying

3n + 8 = 20

Reorder the terms:

8 + 3n = 20

Solving

8 + 3n = 20

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 3n = 20 + -8

Combine like terms: 8 + -8 = 0

0 + 3n = 20 + -8

3n = 20 + -8

Combine like terms: 20 + -8 = 12

3n = 12

Divide each side by '3'.

n = 4

Simplifying

n = 4
