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*(9*x-1)-(-(x-9)-7*x)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  2 • (9x - 1)) -  (9 - 8x)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -10x - 7  =   -1 • (10x + 7) 

Equation at the end of step  3  :

  -10x - 7  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    -10x-7 = 0 

 Add  7  to both sides of the equation : 
                      -10x = 7
Multiply both sides of the equation by (-1) :  10x = -7


Divide both sides of the equation by 10:
                     x = -7/10 = -0.700
