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*(4-x)-(7-3*x)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  5 • (4 - x) -  (7 - 3x)  = 0 

Step  2  :

Equation at the end of step  2  :

  13 - 2x  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -2x+13 = 0 

 Subtract  13  from both sides of the equation : 
                      -2x = -13
Multiply both sides of the equation by (-1) :  2x = 13


Divide both sides of the equation by 2:
                     x = 13/2 = 6.500
