If a + b + c = -2 and x + y = 10,<br> what is -9a + 2x - 9b - 9c + 2y?

MaRussiya [10]

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
