Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  (2 • (6 - 5n))) +  5 • (2 - 7n)  = 0 

Step  2  :

Equation at the end of step  2  :

  (0 -  2 • (6 - 5n)) +  5 • (2 - 7n)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -25n - 2  =   -1 • (25n + 2) 

Equation at the end of step  4  :

  -25n - 2  = 0 

Step  5  :

Solving a Single Variable Equation :

 5.1      Solve  :    -25n-2 = 0 

 Add  2  to both sides of the equation : 
                      -25n = 2
Multiply both sides of the equation by (-1) :  25n = -2


Divide both sides of the equation by 25:
                     n = -2/25 = -0.080
