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*x-(4)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -7x - 4  =   -1 • (7x + 4) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -7x-4 = 0 

 Add  4  to both sides of the equation : 
                      -7x = 4
Multiply both sides of the equation by (-1) :  7x = -4


Divide both sides of the equation by 7:
                     x = -4/7 = -0.571
