Answer:
See all the answers below.
Step-by-step explanation:
by² = d
Jay = 6
ay - cy = d.
cy - b) = y
Option A
by² = d
divide both side by b
y² = d/b
square both sides
y=√d/b
Option B
Jay = 6
Divide both sides by Ja
y= 6/Ja
Option C
ay - cy = d
y(a-c)=d
divide both sides by (a-c)
y= d/(a-c)
Option D
(cy - b) = y
y-cy=-b
y(1-c)=-b
y= -b/(1-c)
