Solution - Linear equations with one unknown

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.1" was replaced by "(1/10)".

Step by step solution :

Step  1  :

             1
 Simplify   ——
            10

Equation at the end of step  1  :

   1
  —— • (50a - 90)  = 0 
  10

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   50a - 90  =   10 • (5a - 9) 

Equation at the end of step  3  :

  5a - 9  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    5a-9 = 0 

 Add  9  to both sides of the equation : 
                      5a = 9
Divide both sides of the equation by 5:
                     a = 9/5 = 1.800
