(x+y)+(x-y)i=7+3i
x+y =7
x-y =3
add these two equations together
x+y =7
x-y =3
------------------
2x = 10
divide by 2
x=5
x+y = 7
5+y =7
subtract 5 from each side
y =2
Answer: x=5
y=2

Answer:
When x = 6.
Step-by-step explanation:
WE need to solve the system:
y = - x^2 + 4x + 4
y = -2x + 4
Equating:
- x^2 + 4x + 4 = -2x + 4
0 = x^2 - 4x - 4 - 2x + 4
x^2 - 6x = 0
x(x - 6) = 0
x = 0, 6.
