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 :

                     -4*(8+5*n)-(8)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  4 • (5n + 8)) -  8  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -20n - 40  =   -20 • (n + 2) 

Equation at the end of step  3  :

  -20 • (n + 2)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -20   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    n+2 = 0 

 Subtract  2  from both sides of the equation : 
                      n = -2
