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 :

                     -118-(-5*(4+7*x)+7)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  -118 -  ((0 -  5 • (7x + 4)) +  7)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   35x - 105  =   35 • (x - 3) 

Equation at the end of step  3  :

  35 • (x - 3)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    35   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    x-3 = 0 

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