Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   5y - 10  =   5 • (y - 2) 

Equation at the end of step  2  :

  15 +  20 • (y - 2)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   20y - 25  =   5 • (4y - 5) 

Equation at the end of step  4  :

  5 • (4y - 5)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    5   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    4y-5 = 0 

 Add  5  to both sides of the equation : 
                      4y = 5
Divide both sides of the equation by 4:
                     y = 5/4 = 1.250
