The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 34i. Which statement must be true about the complex numbers?

Well, a complex number is

a+bi

a=real part

bi=complex part

results in a sum of 34i

aka

0+34i

the sum of 2 complex numbers a+bi+c+di is 34i

therefor

a+c=0 and bi+ci=34i

aka

a=-c

b+c=34

well, the real parts of the complex numbers must be negative of each other and the complex parts must add to 34 should be somewhere around the answer
