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 :

                10*m-3*(2*m-9)-(9*(m-1)+1)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (10m-(3•(2m-9)))-(9•(m-1)+1)  = 0 

Step  2  :

Equation at the end of step  2  :

  (10m -  3 • (2m - 9)) -  (9m - 8)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   35 - 5m  =   -5 • (m - 7) 

Equation at the end of step  4  :

  -5 • (m - 7)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -5   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    m-7 = 0 

 Add  7  to both sides of the equation : 
                      m = 7
