Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -3n + 3  =   -3 • (n - 1) 

Equation at the end of step  2  :

  2 +  -12 • (n - 1)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   14 - 12n  =   -2 • (6n - 7) 

Equation at the end of step  4  :

  -2 • (6n - 7)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -2   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    6n-7 = 0 

 Add  7  to both sides of the equation : 
                      6n = 7
Divide both sides of the equation by 6:
                     n = 7/6 = 1.167
