Step-by-step explanation:
Answer:
P = - 15
Step-by-step explanation:
P+7-5 = -10 - 3
P +2 = - 13
(If taking from one side,you must do to the other to get P alone.)
P+2 = - 13
-2 = - 2
The positive 2, minus the negative 2 cancels each other out, now we must subtract 2 from our other side. - 13 - 2 = - 15
P = -15
we know that
The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign
so
In this problem we have

the conjugate is equal to--------> 
therefore
<u>the answer is the option</u>
10+3i
