Step by step explanation: I'm Sorry this answer is late but here! I don't really get number 2 I'm sorry.

question 1

x=-y

2x-y=-6

x=-y

2(-y)-y=-6

x=-y

y=2

x=-(2

y=2

(-2,2)

x=-2,

y=2

Question 2

-2x + 6y = 30

-2x + 6y + -6y = 30 + -6y

-2x + 0 = 30 + -6y

-2x = 30 + -6y

x = -15 + 3y

x = -15 + 3y
