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*u+10-(-1-9*u+7)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    -u+4 = 0 

 Subtract  4  from both sides of the equation : 
                      -u = -4
Multiply both sides of the equation by (-1) :  u = 4
