Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   15 + 20y  =   5 • (4y + 3) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    5   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    4y+3 = 0 

 Subtract  3  from both sides of the equation : 
                      4y = -3
Divide both sides of the equation by 4:
                     y = -3/4 = -0.750
