Question 30283: 3/7-j=1/2
Answer by Fermat(136)   (Show Source):
You can put this solution on YOUR website! 3/7-j=1/2
Are you trying to find the value of j, yes?
Since there are fractions on both sides, 2 and 7, multiply all three terms by 2*7, which is 14. This gives,
(3/7)*14 - j*14 = (1/2)*14
6 - 14j = 7
subtract 6 from both sides
-14j = 1
14j = -1
j = -1/14
