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 :

                     4*t-(18)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   4t - 18  =   2 • (2t - 9) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    2   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    2t-9 = 0 

 Add  9  to both sides of the equation : 
                      2t = 9
Divide both sides of the equation by 2:
                     t = 9/2 = 4.500
