Answer 1

Answer:D)-1,2

Step-by-step explanation: The lines cross at points (-1,2)

Answer 2

x= 2

y = 20

Explanation:

y = 6x + 8

y = –4x – 2

y = 4 (6x + 8 )

y = 6 (–4x – 2)

y = 24x + 32

y = –24 -12

___________

y = 20

input that back into the equation to find x

20 = 6x + 8

20 - 8 = 6x

12 = 6x

x= 2
