-8(x-3y) when x=-2 and y=-4. To solve the answer, we need to do like this -8(x-3y) Substitute x with -2 and y with -4 -8[-2-3(-4)] =-8(-2+12) =-8(10) =-80 Or -8(x-3y) Use distributive property -8(x)-8(-3y) =-8(x)+24(y) Substitute x with -2 and y with -4 -8(-2)+24(-4) =16-96 =-80. As a result, the correct answer is -80. Hope it help!
