What is j in this equation?

Question

1+j=2(2j=1)

Answer 1

Assuming that you typed the question correctly:

1+j=2(2j=1)

1+j=2(j=1/2)

1+j=(2j=1)

1+j=(j=1/2)

1+j= j =1/2

Therefore, j is no real number.

Answer 2

Hmm, you mistyped the equation, and then put it in the wrong category.  how smart r u?

1+j=2(2j+1)

1+j=4j+2

1=3j+2

-1=3j

j = -1/3
