Answer 1

Ответ:

9+x=18

18-9

x=9

8+y=17

17-8

y=9

18-y=9

18-9

y=9

17-y=9

17-9

y=8

x-8=9

9+8

x=17

y-9=9

9+9

y=18

Answer 2

To solve these equations:

9+х=18

Subtracting 9 from both sides:

х=9

8+y=17

Subtracting 8 from both sides:

y=9

18-y=9

Subtracting 9 from both sides:

y=9

17-y=9

Subtracting 9 from both sides:

y=8

x-8=9

Adding 8 to both sides:

x=17

y-9=9

Adding 9 to both sides:

y=18

Therefore, the solutions to the given equations are:

x = 17 y = 18 х = 9
