To calculate this, you write this as a fraction, -7 / 3i, and multiply top and bottom by i, resulting in -7i / 3i2 = -7i / -3. You shouldn't have trouble continuing the calculation from here.
[7 - 3i] To find the conjugate: the sign of the real part stays the same, and the sign of the imaginary part is reversed. So the conjugate of [7 + 3i] is [7 - 3i]

7
No. But 35 divided by 7 does.
The conjugate is 7 - 3i is 7 + 3i.
