Here's how you solve this problem:
1) Multiply the first equation by 2 (result:2x+2y=8).
2) Add both equations together (result:2x+x+2y-2y=8-5)
3) Simplify (result:3x=3)
The answer is 3x=3.
This could be simplified more, however, to equal x=1, since both sides are divisible by 3.
p.s. Have a good day!
