9. -6+6=0 0+3=3 therefore -6+9=3
x-6=9 With this problem you have to isolate (Leave it by itself) X. In order to do this, You need to take away the -6, correct? to get rid of the -6, you have to add 6 to the left side. In algebra you always need to know, whatever you do to one side, you need to do to the other. So, then you add 6 to the 9. Then, you're left with x=15. Wa, La! In simpler terms, x-6=9 +6, +6 x=15
you need to add +9 +9-7 = +2
You need to add 12.
You need to add 6 - (-9) = 6 + 9 = 15.
9 - (-6) = 9 + 6 = 15
The next number would be 18.3, 4, 6, 9, 13To get from 3 to 4, you need to add one. To get from 4 to 6, you need to add two. To get from 6 to 9, you need to add three. And so on and so on.

You will add -3 to 9 to make it 6.
you need to add +9 +9-7 = +2
You need to add 12.
4 6 9 13 18 24 31 39 ...... Add 2 to 4 to get 6 then add 3 to 6 to get 9 then add 4 to 9 to get 13 and so on.
3
we will add -3 :)
