Answer:
x=3 and y=2
Step-by-step explanation:
These equations line up quite nicely, so let's use the elimination method.
x+y=5
+ x-y=1
-------------
2x=6.
Now that we added the two equations together, we only have x as a variable to solve. We now divide 2 from both sides
x=3.
Now we take our 3 and substitute it into one of the equations. I want to put it in the first one.
3+y=5.
We subtract 3 from both sides to get y=2.
We end up with the answers x=3 and y=2. If you plug them in to check, they make sense. 3+2=5 and 3-2=1. This answer is proven to be correct.
Have a nice day :)
