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+8)-(2*x-7+8*(x-1))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (5 • (x + 8)) -  ((2x - 7) +  8 • (x - 1))  = 0 

Step  2  :

Equation at the end of step  2  :

  5 • (x + 8) -  (10x - 15)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   55 - 5x  =   -5 • (x - 11) 

Equation at the end of step  4  :

  -5 • (x - 11)  = 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-11 = 0 

 Add  11  to both sides of the equation : 
                      x = 11
