Answer:

 values of j are: 2 , -1

Step-by-step explanation:

We have been given:

[tex]\frac{j+4}{j+2}={2}-\frac{1}{j}[/tex]

We will cross multiply in the above equation we get:

[tex]\frac{j+4}{j+2}=\frac{2j-1}{j}[/tex]

[tex]j^2+4j=2j^2+4j-j-2[/tex]

[tex]2j^2-j^2+4j-4j-j-2[/tex]

[tex]j^2-j-2[/tex]

We will solve the quadratic equation by factorizing:

[tex]j^2-2j+j-2[/tex]

[tex]j(j-2)+1(j-2)[/tex]

[tex](j+1)(j-2)[/tex]

hence, the values of j are: 2 , -1
