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 :

                     35+7*x-(-3*(-5-4*x))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -5 - 4x  =   -1 • (4x + 5) 

Equation at the end of step  2  :

  (7x + 35) -  (0 -  -3 • (4x + 5))  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   20 - 5x  =   -5 • (x - 4) 

Equation at the end of step  4  :

  -5 • (x - 4)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -5   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x-4 = 0 

 Add  4  to both sides of the equation : 
                      x = 4
