-6.93+12.1j-7.3j=2.19
Subtract 7.3j from both sides.
-6.93+4.8j=2.19
Combine 12.1j and -7.3j to get 4.8j.
4.8j=2.19+6.93
Add 6.93 to both sides.
4.8j=9.12
Add 2.19 and 6.93 to get 9.12.
j=\frac{9.12}{4.8}
Divide both sides by 4.8.
j=\frac{912}{480}
Expand \frac{9.12}{4.8} by multiplying both numerator and the denominator by 100.
j=\frac{19}{10}
Reduce the fraction \frac{912}{480} to lowest terms by extracting and canceling out 48.
