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.
