Homework Help: RADICAL EQUATIONS

Posted by AMY on Thursday, January 27, 2011 at 6:56pm.

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=64-2y
add 2y to each side.
8y=64
