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 :

                     -7*(7*z-1)-(7-4*z)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  7 • (7z - 1)) -  (7 - 4z)  = 0 

Step  2  :

Equation at the end of step  2  :

  -45z  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -45z = 0 

 Multiply both sides of the equation by (-1) :  45z = 0


Divide both sides of the equation by 45:
                     z = 0
