Question

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 ?

Answer 1

To get x by itself, you have to get rid of the nine, so add nine to both sides.
Now what do you have?

Answer 2

Thanks :)

Answer 3

You already figured it out? :p

Answer 4

Would it be -2/5 < 9/10 then?

Answer 5

No... you are solving for x, correct?

Answer 6

-2/5x < 9/10 + 9
-2/5x < 99/10
-2x < 99/10 (5)
-2x < 99/2
x < -99/4

Answer 7

Yeah I am

Answer 8

-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

Answer 9

Thanks soo much! :)
