step-by-step explanation:

idk i would have to be there to under stand it

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
