Question

-9-4(2-y)+1

Answer 1

-9-4(2-y)+1
-9-8+4y+1 (PEMDAS.. Distribute -4 to (2-y) -4(2) = 8 -4(-y) = 4y)
-16+4y=0 (Simplify)
4y=16 (Transpose)
y=4 (Divide 16 by 4)

Answer 2

how did you get the -16

Answer 3

-9-8 = -17 you go 8 units back from -9 so (-10,-11,-12,-13,-14,-15,-16,-17)
-17+1= -16 you go 1 unit forward from -17 (-16)

or just follow the rules of integers.
