4-3x = 7x-6+2x

4-3x = 9x-6

4-12x = -6

-12x = -10

x = 0.8333333

Is that right?

What is the book's answer?  So you plug the answer in as x and it doesn't work?  Then obviously the answer in the book is a typo.

Quoting ElitestJen:

You beat me to it, but you used decimals in your final answer so I'll count that as a win.
