4 + 3n = 111

Solving
4 + 3n = 111

Solving for variable 'n'.

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

Add '-4' to each side of the equation.
4 + -4 + 3n = 111 + -4

Combine like terms: 4 + -4 = 0
0 + 3n = 111 + -4
3n = 111 + -4

Combine like terms: 111 + -4 = 107
3n = 107

Divide each side by '3'.
n = 35.66666667

Simplifying
n = 35.66666667
