You can put this solution on YOUR website! Just take each expression separately and use logic. Take out  first. Ask yourself, what plus ten would give me zero? You should get -10. Then take  . Ask yourself, what minus 4 would give me zero? You should get 4. Lastly, take  . Again, ask yourself, what plus 6 would give me zero? You should get -6. Which one of your answers is the highest number, -10, 4, or -6? Your answer to that question is four. So since 4 is your answer, separate the equation that got you that answer to (x-4) and work with it. Kick the other friends to the curb. set it up as  . Then since your original equation is an inequality, change the equal sign to a more than sign.  . Then as you know from before, x=4, but this time, it is altered to  . So this is your final answer that when plugged into the original equation would make the inequality true.
