Answer:
x = 3, y = 1
(3,1)
Step-by-step explanation:
Elimination is a method of solving systems where we add or subtract the two equations to "eliminate" one of the variables.
Take a look at our system. We have a -y and a +y. If we added those together, they would cancel!
-x- y=-4
-2x+y=-5 +
--------------
-3x + 0y = -9
It worked! No more y. Solve for x!
-3x = -9
x = 3
Plug x back in to get y.
-x - y = -4
-3 - y = -4
-y = -1
y = 1
