vodomira [7]4 years ago
4 0

Answer:

n = -4

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((6n -  2 • (4n + 7)) +  4) -  -2  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -2n - 8  =   -2 • (n + 4)

Equation at the end of step  3  :

 -2 • (n + 4)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    n+4 = 0

Subtract  4  from both sides of the equation :

                     n = -4

One solution was found :

                  n = -4
