Step-by-step explanation:
If x=3, y=7 when x+y=z
z=3+7
z=10

Step-by-step explanation:
Solving the following system of equations:

Let

Putting value of x^2 in eq(2)

Now, finding value of x
Putting y=-5

y=-5, x= 2i and y=-5 , x= -2i
Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer
Putting y=3

So,
