The sum of two numbers is 33 and their difference is 2. What are the numbers?
\left \{ {{x+y=33} \atop {x-y=2}} \right.  \\  \\ \left \{ {{y=33-x } \atop {x-y=2}} \right.  \\  \\\left \{ {{y=33-x } \atop {x-(33-x) =2}} \right.  \\  \\ x-33+x= 2 \\  \\ x+x= 2+33\to 2x= 35\to x= 17,5 \\  \\  \\ y= 33-x\to y= 33-17,5\to y= 15,5

I wish you much success in your studies!!!!

I would say that it would be a fraction
like 15 1/2 and 17 1/2
cause 15 +17 =32 and 1/2 + 1/2 =2/2 which is 1
32+1=33
Now 17 1/2 - 15 1/2
17-15=2 and 1/2 - 1/2 =0
So the answer could be 15 1/2 and 17 1/2
