Answer:
x = 1, y = -1
Step-by-step explanation:
If we have the two equations:
and , we can look at which variable will be easiest to eliminate.
looks like it might be easy to get rid of, we just have to multiply by 2 and y is gone (as -6y + 6y = 0).
So let's multiply the equation by 2.
Now we can add these equations
------------------------
Dividing both sides by 5, we get .
Now we can substitute x into an equation to find y.
