Question

The sum of two numbers is x. If one of the numbers is 12, what is the other?

Answer 1

umm that question seems illogical but it said sum so do addition so i say c

Answer 2

Hey there !

The Sum is basically addition

Of two numbers, that is a number and 12.

We don't know what your unknown number is so will put it as "X"

and 12 = 12


Therefore,
`12 + x` (option C) would mostly be your result because it is the sum of those two numbers

Good luck on your assignment and enjoy your day!
