Answer:
Step-by-step explanation:
-3x + 4y = -18
8x - 4y = 28
5x = 10
x = 2
4 - y = 7
-y = 3
y = -3
(2, -3)
16-4=12
8x=12
÷8
x=12/8
x=3/2
x=1.5
Answer:
A and D
Step-by-step explanation:
By finding the roots of all the equations, we see that options A and D are the only ones that require an imaginary number in order to solve
