Isiah Bauer · Answer 1

If you plug in y=-21 and x=3 into each answer choice, you'll find the answer.

A) - 7 (3) = - 21 True

B) - 21/3 = 7 True

C) 3/-21 = 7 False

D) 3 x - 21 = - 7 False

Elsa Foster · Answer 2

A. - 7x=y

Because if you multiply - 7 by x. - 7 x 3 = - 21. - 21 is your y term

B. y/x=-7

Because if you divide Y by X. - 21/3=7
