Answer:

X= -5, Y= 16/3

Step-by-step explanation:

Okay, first line dem up:

-5x+3y=-19

-x-3y=-11

We can add, so -5x plus -x is -6x Y gets cancelled out, and -19 plus -11 is -30. So our equation is:

-6x=-30

This means that x equals -5, and now we substitute the answer in an equation to find "y". I chose equation 2. So with x factored in, it's:

5-3y=-11

Subtract both sides by 5.

-3y=-16

And we get: y= 16/3
