Solve for n.

19n - 9n - 8n = 12

A. n = 4

B. n = 0

C. n = 10

D. n = 6

D. n=6

Step-by-step explanation:

19n - 9n - 8n = 2n

so 2n=12

so 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
