ok both sides of the eqaution actually equaly 29 but you just need to work out what the j is so keep in mind whatever you do to one side you do to the other
29=14 +3j
first get rid of the 14 so you minus it - from both sides so:
15 = 3j
the 3 and the j have been multiplied together to make 3j so to get rid of the 3 and only find out what 1j or j eqaul you do the opposite and divide them by 3:
5 = j or j = 5
remeber how i said both sides eqaul 29? with the answer back in you can prove it.
29= 14 + 3j
29= 14 + (3x5)
29= 14 +15
29=29

29=14+3j
1. get j by itself
2. 29=14-14+3j
3. 29-14=3j
4. 15=3j
5, 15/3=3j/3
6. 3=j

Do to one side what you do to the other.
29-14 = 14+3j-14
15 = 3j
15/3 = 3j/3
5 = j

your trying to figure out what 'j' is.
29=14=3j
29-14=3j
5=j <15 divided by 3 is 5
so j=5
tah-dah!=)
hope i helped
