- 10 + x = 3 Add 10 to both sides: 0 + x = 3 + 10 or x = 13
-10
You add 10 to -7 to get 3.
3
if ya add 10 u get zero, so add 13 n u get 3......which grade are u in btw :P
you need to add 3/10 to 7/10 to get 10/10 or 1.

Starting with 85, if you add 7, you get 92. Then, if you increase the number you add by 3 each time, you would add 10 (7+3) to 92, resulting in 102. Continuing this pattern, you would add 13 (10+3) to 102, resulting in 115, and so on.
The idea is to add 1 + 3/10.
10.
just add 10 multiply by 3 add your age and double it
