Solution - Linear equations with one unknown

Rearrange:

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

                     7*(8-8*n)-(-112)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   8 - 8n  =   -8 • (n - 1) 

Equation at the end of step  2  :

  -56 • (n - 1) -  -112  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   168 - 56n  =   -56 • (n - 3) 

Equation at the end of step  4  :

  -56 • (n - 3)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -56   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 5.2      Solve  :    n-3 = 0 

 Add  3  to both sides of the equation : 
                      n = 3
