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*(2*y+7)-(20)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  5 • (2y + 7) -  20  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   10y + 15  =   5 • (2y + 3) 

Equation at the end of step  3  :

  5 • (2y + 3)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    5   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    2y+3 = 0 

 Subtract  3  from both sides of the equation : 
                      2y = -3
Divide both sides of the equation by 2:
                     y = -3/2 = -1.500
