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 :

                     -3-(7*(y-79))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  -3 -  7 • (y - 79)  = 0 

Step  2  :

Equation at the end of step  2  :

  550 - 7y  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -7y+550 = 0 

 Subtract  550  from both sides of the equation : 
                      -7y = -550
Multiply both sides of the equation by (-1) :  7y = 550


Divide both sides of the equation by 7:
                     y = 550/7 = 78.571
