Solve for n.
19n - 9n - 8n = 12
A. n = 4
B. n = 0
C. n = 10
D. n = 6

The answer is n=6

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  2n - 12  =   2 • (n - 6)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    n-6 = 0

Add  6  to both sides of the equation :

                     n = 6

One solution was found :

                  n = 6
