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 :

                9*(3-2*x)-(2*(10-8*x))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   10 - 8x  =   -2 • (4x - 5) 

Equation at the end of step  2  :

  (9 • (3 - 2x)) -  -4 • (4x - 5)  = 0 

Step  3  :

Equation at the end of step  3  :

  9 • (3 - 2x) -  -4 • (4x - 5)  = 0 

Step  4  :

Equation at the end of step  4  :

  7 - 2x  = 0 

Step  5  :

Solving a Single Variable Equation :

 5.1      Solve  :    -2x+7 = 0 

 Subtract  7  from both sides of the equation : 
                      -2x = -7
Multiply both sides of the equation by (-1) :  2x = 7


Divide both sides of the equation by 2:
                     x = 7/2 = 3.500
