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*x-(2*(x-4))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  7x -  2 • (x - 4)  = 0 

Step  2  :

Equation at the end of step  2  :

  5x + 8  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    5x+8 = 0 

 Subtract  8  from both sides of the equation : 
                      5x = -8
Divide both sides of the equation by 5:
                     x = -8/5 = -1.600
