add -10... 11 + (-10) = 11-10=1 ur welcome! So that would be 2x + 11 = 1 where x = -5.
1 p.m. (13.00) because then it will be 11 a.m. add 2 hrs
you can add Mod 12, this is like clock math. If it is 11 o'clock and you add 2 hours, it is then 1 o'clock. This is called addition Mod 12.
2x - 3y = 4 x + 4y = 3 Write the augmented matrix: 2 -3 4 1 4 3 Multiply the first row by 1/2: 1 -3/2 2 1 4 3 Subtract the second row from the first row: 1 - 3/2 2 0 -11/2 -1 Multiply the second row by -2/11: 1 -3/2 2 0 1 2/11 Multiply the second row by 3/2 and add it to the first row: 1 0 25/11 0 1 2/11 Thus x = 25/11 and y = 2/11 Check:
To take the 2's complement:Invert 1's and 0's (change each 1 to a 0, and each 0 to a 1).Add 1 to the result.
2 + 171=173 1 + 7 + 3 = 11 < 18

add 2 hr and 11 hrs and get get 1 o'clock
Is this a riddle? IDK, add 11 and 2 and you get 13, which is ONE answer? Or maybe if you add 11 and 2 and divide all of that by by 13, or take 13^0?

because if you add 1 to 12 you will get one more not less.

To get from 2 to 5 you are multliplying 2 by 2 and adding 1. The difference is 3. Now, to get from 5 to 11 you do the same thing - multipy 5 by 2 and add 1 to get 11. That's what you do to 23. Multlipy by 2 and add 1 to get 47.
Add (2 y - 1) to both sides to result in x - 1 = 2 y; divide by 2 to result in y = (x - 1)/2.
2/15 + 1 + 7/10 = 11/6
At least 11 of them.
11/15
1, 2, 3....11, 12, 13.
