-3x+y=-5 x+2y=0

Question

Your equations:
-3x + y = -5
x + 2y = 0

Let's solve the second equation for x:
x = -2y

Now let's substitute -2y for x in the first equation to solve for y:
-3(-2y) + y = -5
6y + y = -5
7y = -5
y = -5/7

Now let's substitute -5/7 for y in the second equation to solve for x:
x + 2(-5/7) = 0
x + -10/7 = 0
x = 10/7

Check these values with the original equations. It always helps to check your work!

I hope this will help.
