Final answer:
The number that when added to negative one gives thirty-five is 36. This is determined by solving the algebraic equation x + (-1) = 35, which simplifies to x = 36.
Step-by-step explanation:
The question asks us to find a number such that when added to negative one, the result is thirty-five. This can be set up as an algebraic equation:
x + (-1) = 35
To solve for x, we need to isolate it on one side of the equation:
x = 35 + 1
x = 36
The number we are looking for is 36.
