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 :

                3*(-3*b+10)-(-6*b-10+5*b)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  3 • (10 - 3b) -  (-b - 10)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   40 - 8b  =   -8 • (b - 5) 

Equation at the end of step  3  :

  -8 • (b - 5)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -8   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    b-5 = 0 

 Add  5  to both sides of the equation : 
                      b = 5
