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 :

                     -5*(x+4)-(-2*(2*x+1))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0-(5•(x+4)))-(0-2•(2x+1))  = 0 

Step  2  :

Equation at the end of step  2  :

  (0 -  5 • (x + 4)) -  -2 • (2x + 1)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -x - 18  =   -1 • (x + 18) 

Equation at the end of step  4  :

  -x - 18  = 0 

Step  5  :

Solving a Single Variable Equation :

 5.1      Solve  :    -x-18 = 0 

 Add  18  to both sides of the equation : 
                      -x = 18
Multiply both sides of the equation by (-1) :  x = -18
