If a + b + c = - 2 and x + y = 10,

what is - 9a + 2x - 9b - 9c + 2y?

38

because since all abc and xy have the same coefficients it makes it easier.

i just made a=-2, b=-4, and c=4 because when added up it equals - 2

i also made both x and y = 5 becasue when added up it equals 10

so, - 9 (-2) + 2 (5) - 9 (-4) - 9 (4) + 2 (5)

18+10+36-36+10=38
