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*(y+9)-(12*y+13)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  3 • (y + 9) -  (12y + 13)  = 0 

Step  2  :

Equation at the end of step  2  :

  14 - 9y  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -9y+14 = 0 

 Subtract  14  from both sides of the equation : 
                      -9y = -14
Multiply both sides of the equation by (-1) :  9y = 14


Divide both sides of the equation by 9:
                     y = 14/9 = 1.556
