Best ResponseYou've already chosen the best response.0To get x by itself, you have to get rid of the nine, so add nine to both sides. Now what do you have?

Best ResponseYou've already chosen the best response.02/5x  9 <9/10 is the original equation. Now you add nine to both sides to get rid of the nine. (2/5x9)+9 < (9/10) +9. Simplify now you have 2/5x < 9 9/10 Now to get rid of the fraction 2/5, multiply both sides by 5 You now have 2x < 40 9/10 Then to get x by itself, divide both sides by 2. Remember that when you divide an inequality by a negative number the sign switches, so the equation is now: x> 20 9/10
