Question

6 - 3n = -12 what is n?

Answer 1

Answer: 6

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6-3*n-(-12)=0  

Step  1  :

Pulling out like terms :

Pull out like factors :

18 - 3n  =   -3 • (n - 6)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -3   =  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

Answer 2

Answer: n = 6

Step-by-step explanation:

6 - 3n = -12

Collect like terms

-3n = -12-6

-3n = -18

Divide both side by -3

-3n/-3 = -18/-3

n = 6
