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 :

                     12-y-(5)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    -y+7 = 0 

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