Answer:

-1

Explanation:

2 - (-4) + (-y)

plug in 7 as y

2 - (-4) + (-7)

so you start with the first addition/subtraction (PEMDAS)

also the negative is distributed to the -4 make it positive, a negative and a negative equals a positive, therefore positive 4

2 - (-4) = 6

or

2 + 4 = 6

then... the equation reads

6 + (-7) = -1

*becareful -7 is "more than/ more negative than" 6 making the answer a negative
