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 :

                     -3*(-u-1)-(-4+2*u)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -u - 1  =   -1 • (u + 1) 

Equation at the end of step  2  :

  (0 -  -3 • (u + 1)) -  (2u - 4)  = 0 

Step  3  :

Equation at the end of step  3  :

  u + 7  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    u+7 = 0 

 Subtract  7  from both sides of the equation : 
                      u = -7
