Answer:

X= -3

Y= 7

a= -6

b = -28

C = 9

D= -7

Step-by-step explanation:

2x – 4y = -34

-3x - y = 2

2x – 4y = -34

-12x - 4y = 8

-14x = 42

X= 42/-14

X= -3

-3x - y = 2

-3(-3) -y = 2

9-y = 2

9-2= y

Y= 7

a = 2x

a= 2*-3

a= -6

b = -4y

b = -4*7

b = -28

C= -3x

C= -3*-3

C = 9

D= -y

D= -7
