Answer 1

1)х=17-8
   х=9

2)-у=8-20
   -у=-12/-1
    у=12

Answer 2

Х+8=17
х=17-8
х=9

20-у=8
-у=8-20
у=12

Answer 3

I can help you solve the equation x + 8 = 17 + 20 - y = 8. Here are the steps:

- First, we need to isolate x on one side of the equation. To do that, we can subtract 8 from both sides. This gives us x = 9 + 20 - y. - Next, we can simplify the right side by adding 9 and 20. This gives us x = 29 - y. - Finally, we can solve for y by adding y to both sides and subtracting x from both sides. This gives us y = 29 - x.

Therefore, the solution is x = 29 - y and y = 29 - x. You can check this by plugging in any value for x or y and seeing if the equation is true.
