Answer:
Step-by-step explanation:
A
X= -5, Y= 16/3
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
I hope that this answer help you.
