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 :

                     7*(2-m)-(3*m)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  7 • (2 - m) -  3m  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   14 - 10m  =   -2 • (5m - 7) 

Equation at the end of step  3  :

  -2 • (5m - 7)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -2   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    5m-7 = 0 

 Add  7  to both sides of the equation : 
                      5m = 7
Divide both sides of the equation by 5:
                     m = 7/5 = 1.400
