Answer:

n = 5

Step-by-step explanation:

3n + 7 = 22

Solve for n.

----------------------

When we need to find a variable, we need to isolate the variable to the point that it is by itself.

3n + 7 = 22

Subtract 7 from both sides :

3n + 7 - 7 = 22 - 7

3n = 15

Divide both sides by 3 :

n = 5
