Question

Please help me i got this wrong and i’m wondering what’s the right answer

Answer 1

We have the next statement

`(\text{?}-3i)-(15-?i)=7-12i`

For the first unknown value, we need to find a number that subtracting 15 is equal to 7. That number is 22.

For the second unknown value, -3 minus the unknown value is equal to -12. Therefore the result is 9.
