I am going to be blundt- this is a pretty simple question. I recommend looking at YouTube or Khan Academy videos on simulataneous linear equations if you are having trouble with this.

Try adding the two equations, solving for x, and plugging your x value back into one of the equations.

Please try and digest my process, or you won't learn anything. Happy trails!

If you are OP, the first answer by that Guest was most likely a troll. I will reitirate what I said in my answer - this problem is very basic. You didn't even take the time to check if the Guest's answer was right, which means you are literally just here for a shortcut to your homework. I recommend actually attempting the problem before coming here.

If you are still having issues, I have posted some hints to the process of this equation in my answer (#2), hope it helps.
