Answer:

C) 1/2 and 8

Explanation:

-2x + y = 7 Eq. 1

6x + y = 11 Eq. 2

From Eq. 1:

y = 7 + 2x Eq. 3

From Eq. 2:

y = 11 - 6x Eq. 4

Equalyzing Eq. 3 and Eq. 4:

7 + 2x = 11 - 6x

2x + 6x = 11 - 7

8x = 4

x = 4/8

x = 1/2

From Eq. 3:

y = 7 +2* 1/2

y = 7 + 1

y = 8

Check:

From Eq. 2

6x + y = 11

6*1/2 + 8 = 11

3 + 8 = 11
