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 :

                     -5*x+4-(-4*x+9)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -x - 5  =   -1 • (x + 5) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -x-5 = 0 

 Add  5  to both sides of the equation : 
                      -x = 5
Multiply both sides of the equation by (-1) :  x = -5
