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*(5*x+2)+2*x+4-(50)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (((0 -  4 • (5x + 2)) +  2x) +  4) -  50  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -18x - 54  =   -18 • (x + 3) 

Equation at the end of step  3  :

  -18 • (x + 3)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -18   =  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 

 Subtract  3  from both sides of the equation : 
                      x = -3
