12
-9 + x = 3
-9 + x + 9 = 3 + 9
x = 3 + 9
x = 12
9. -6+6=0 0+3=3 therefore -6+9=3
you need to add +9 +9-7 = +2
Add -3 to 9 because 9+(-3) = 6 Alternatively add s to the Roman numeral of ix which is 9 which then becomes six.
-3 (-2times8)=-16 to get to -7 you need to add 9 So if the other value is-3x, you need a -3 to equal a +9
-9 + 11 = 2
9. -6+6=0 0+3=3 therefore -6+9=3
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 need to add 6 - (-9) = 6 + 9 = 15.
you need to add +9 +9-7 = +2
Add -3 to 9 because 9+(-3) = 6 Alternatively add s to the Roman numeral of ix which is 9 which then becomes six.
3
-8
You will add -3 to 9 to make it 6.
10 - (-9) = 19
It is: -9+16 = 7
-9 + 11 = 2
- 8 + 17 = 9 =========
