Can someone solve these two questions for me ASAP? 12 points!

Please solve for x and y thanks!

-7x+y=-2

and

x-3y=7

Thank you!

I believe that you are talking about simultaneous equations? Then in that case, using the elimination method(Singapore syllabus person):

-7x+y=-2 —(1)

x-3y=7–(2)

(1)x3:
3(-7x+y)=3(-2)
-21x+3y=-6 —(3)

(2)+(3):

x-3y-21x+3y=7-6

-20x=1
x =-1/20

Substitute x=-1/20 into (2)

-1/20-3y=7
151/20=3y
y=-2.35

You could also use the graphical method and find the intersection for your x and y.
