Given the equaton:

3n - 4 = 11

Solve for n.

Solution:
In order to solve for n, we simply need to transpose - 4 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

3n - 4 = 11

3n = 4 + 11

3n = 15

Divide both sides by 3 in order to determine the value of n.

3n/3 = 15/3

n = 5

Final answer:

n = 5
