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 :

                     2*s+4-(5*(-4-2*s))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -4 - 2s  =   -2 • (s + 2) 

Equation at the end of step  2  :

  (2s + 4) -  -10 • (s + 2)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   12s + 24  =   12 • (s + 2) 

Equation at the end of step  4  :

  12 • (s + 2)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    12   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    s+2 = 0 

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