Solution - Linear equations with one unknown

j=4
j=4

Step by Step Solution

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                -20*j+6*j+18*j-9*j+17-(-3)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -5j + 20  =   -5 • (j - 4) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -5   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    j-4 = 0 

 
Add  4  to both sides of the equation : 
 
                     j = 4

One solution was found :

                   j = 4
