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*(3*n+5)-(9*(7*n+5)+3)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (5 • (3n + 5)) -  (9 • (7n + 5) +  3)  = 0 

Step  2  :

Equation at the end of step  2  :

  5 • (3n + 5) -  (63n + 48)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -48n - 23  =   -1 • (48n + 23) 

Equation at the end of step  4  :

  -48n - 23  = 0 

Step  5  :

Solving a Single Variable Equation :

 5.1      Solve  :    -48n-23 = 0 

 Add  23  to both sides of the equation : 
                      -48n = 23
Multiply both sides of the equation by (-1) :  48n = -23


Divide both sides of the equation by 48:
                     n = -23/48 = -0.479
