Hello from MrBillDoesMath!
Answer:
y = x/15
Discussion:
Given:
2x/5y = 6 => (multiply both sides by 5y)
(2x/5y) 5y = 6 * (5y) =>
2x = 30y => (divide both sides by 30)
(2/30)x = y =>
y = x/15
( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)
Thank you,
MrB
