find the value of y in the modular 11 system. 10+y = 1

y = -9 = 2

is it -9 or 2

-9 and 2 represent the same number in the number system Modulo 11.

To find the value of y in the modular 11 system, we need to solve the equation 10 + y = 1.

To isolate y, we'll subtract 10 from both sides of the equation:

10 + y - 10 = 1 - 10

Simplifying the equation gives:

y = -9

However, in the modular 11 system, we only consider values between 0 and 10. Therefore, we need to find the equivalent value of -9 within this range.

To do this, we add 11 to -9 until we get a value within the range of 0 to 10:

-9 + 11 = 2

Therefore, the value of y in the modular 11 system is 2.
