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 :

                     2*(3*w-4)-(7)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  2 • (3w - 4) -  7  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   6w - 15  =   3 • (2w - 5) 

Equation at the end of step  3  :

  3 • (2w - 5)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    2w-5 = 0 

 Add  5  to both sides of the equation : 
                      2w = 5
Divide both sides of the equation by 2:
                     w = 5/2 = 2.500
