Question

Assume that y varies directly with x, then solve. if y=-16 when x=4, find x when y=20

Answer 1

Answer: If you divide -16 by 4 that will equal 4, so you divide 20 by 4, which will get you -5. That means the answer is

x = -5

Answer 2

If you divide 16 by 4 that will equal 4, so you divide 20 by 4, which will get you 5. That means the answer is

X=5
