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 :

                     -10-(10*(k-9))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  -10 -  10 • (k - 9)  = 0 

Step  2  :

Pulling out like terms :

 2.1      Pull out     -10 

Note that  10 =(-1)• -10 
After pulling out, we are left with :
      -10 • ( (-1) +( (-1)  *  (k-9) ))

Equation at the end of step  2  :

  -10 • (8 - k)  = 0 

Step  3  :

Equations which are never true :

 3.1      Solve :    -10   =  0

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

Solving a Single Variable Equation :

 3.2      Solve  :    -k+8 = 0 

 Subtract  8  from both sides of the equation : 
                      -k = -8
Multiply both sides of the equation by (-1) :  k = 8
