I don't just want the answer. I'm just confused as to the steps for this... :/ can someone help please? -2/5x - 9 <9/10 ?
To get x by itself, you have to get rid of the nine, so add nine to both sides. Now what do you have?
You already figured it out? :p
Would it be -2/5 < 9/10 then?
No... you are solving for x, correct?
-2/5x < 9/10 + 9 -2/5x < 99/10 -2x < 99/10 (5) -2x < 99/2 x < -99/4
-2/5x - 9 <9/10 is the original equation. Now you add nine to both sides to get rid of the nine. (-2/5x-9)+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
