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 :

                     400-3*t-(180+5*t)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   220 - 8t  =   -4 • (2t - 55) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -4   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    2t-55 = 0 

 Add  55  to both sides of the equation : 
                      2t = 55
Divide both sides of the equation by 2:
                     t = 55/2 = 27.500
