13 add something equals 30 = 43

-43
If you mean adding in groups, I suppose you could break 34 into 30 and 4. Then you could add 9 to 4 to get 12, and then perhaps more easily add 13 and 30 to get 43.
It is: 13+17 = 30
30 - 3 = 40 - 13
Add them together which equals 59
-17

How about: 23+7 = 30 or 17+13 = 30
2x-17=13 2x=30 x=15
1x30
Add them together which equals 59
30 - 3 = 40 - 13
It is: 13+17 = 30
x=30...9+30=39 then divide by 3 equals 13.

No, it is -5/13
