Homework Help: Algebra

Posted by Juri on Monday, July 23, 2007 at 10:25am.

There are two solutions to | 16x - 5 | = 3. The greatest solution is ___.

Since the expression, 16x - 5, can be either positive or negative, solve for both.

16x - 5 = 3

16x = 8

x = .5

-(16x - 5) = 3

-16x + 5 = 3

-16x = -2

x = 1/8

You can decide which is "greatest."

I hope this helps. Thanks for asking.
