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+2)-(x+2)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  7 • (x + 2)) -  (x + 2)  = 0 

Step  2  :

Pulling out like terms :

 2.1      Pull out     x+2 

After pulling out, we are left with :
      (x+2) • ( (-7)  *  1 +( (-1) ))

Equation at the end of step  2  :

  -8 • (x + 2)  = 0 

Step  3  :

Equations which are never true :

 3.1      Solve :    -8   =  0

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

Solving a Single Variable Equation :

 3.2      Solve  :    x+2 = 0 

 Subtract  2  from both sides of the equation : 
                      x = -2
