Answer:
20
Step-by-step explanation:
From if y=-7 when x=-14 ----> x=2y
that means when y=10, x=20
Answer: X = 20
Step-by-step explanation:
Y = KX (where K is the proportionality constant as y varies directly with X)
-7 = -14 K
K = -7/-14
K = 0.5
Hence finding X when Y is 10
Y = 0.5 X
10 = 0.5X
X = 10/0.5
X= 20
