Answer:

n = -7

Step-by-step explanation:

One solution was found :

                  n = -7

Rearrange:

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

                    8*(1+n)-(-20+4*n)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 8 • (n + 1) -  (4n - 20)  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  4n + 28  =   4 • (n + 7)

Equation at the end of step  3  :

 4 • (n + 7)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    n+7 = 0

Subtract  7  from both sides of the equation :

                     n = -7

One solution was found :

                  n = -7
