please help me I started dating my girlfriend. she asked me out and I felt obligated to say yes. I had my first kiss with her. then she decided she was non-bianary. then they broke up with me because she didn't like me anymore. she still wanted to be my friend though. It was going all well until they started hitting on my best friend. what should I do?

The numbers 18/0, 18/8 and 18/10 refer to the percentages of chromium and nickel in the stainless steel alloy. The "18" refers to the chromium content, which gives flatware its rust-resistance properties, and the "8" or "10" refers to the nickel content, which gives it its silver-like shine and some rust-resistance.

x+y=18

x-y=8

We can then use elimination to get just one variable.

 x+y=18

+x-y=  8

Which gives us:   2x=26

We then divide by 2 and get:    x=13

We next plug that into one of the two equations and solve for the other variable:    (13)+y=18

We subtract 13 from both sides and get:   y=5

So the two numbers are 13 and 5.
