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*(y-10)-(-5)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  5 • (y - 10) -  -5  = 0 

Step  2  :

Pulling out like terms :

 2.1      Pull out     5 

Note that  -5 =(-1)• 5 
After pulling out, we are left with :
      5 • ( (-1)  *  (y-10) +( (-1) ))

Equation at the end of step  2  :

  5 • (9 - y)  = 0 

Step  3  :

Equations which are never true :

 3.1      Solve :    5   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 3.2      Solve  :    -y+9 = 0 

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