RADICAL EQUATIONS
posted by AMY .
PLEASE HELP! I have the steps down and an answer..just need the correct one.
6/8 = 8/y  1/2
The LCM here is 8y, so I multiply on both sides by 8y.
8y times 6/8 = 8y times 8/y  8y times 1/2.
After canceling out, I have 6y = 64  4y. Combine like terms.
2y = 64; y = 32?
Thank you!

No, when you combine like terms, you erred.
6y=642y
add 2y to each side.
8y=64 
Ah! I see. Thank you!
