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*(-4*x-1)-x+3-(-30)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -4x - 1  =   -1 • (4x + 1) 

Equation at the end of step  2  :

  (((0 -  -2 • (4x + 1)) -  x) +  3) -  -30  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   7x + 35  =   7 • (x + 5) 

Equation at the end of step  4  :

  7 • (x + 5)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    7   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x+5 = 0 

 Subtract  5  from both sides of the equation : 
                      x = -5
