Answer:

y =-1

Last option is correct.

Explanation:

The given equation is
9+y=8

In order to solve for y, we need to isolate y.

In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.

The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation


9+y-9=8-9

On simplifying, we get


y=-1

Hence, value of y is -1

Last option is correct.
