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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
