Question

CAN SOMEONE SHOW ME STEP BY STEP?!?

Answer 1

So first let’s multiply both sides by 10
Now we are left with this:
-4x-90<9

Now you want to move the -90 to the other side and when you do this you have to change the sign as well so now you have this:
-4x<9+90

Now add 9 and 90 together and you’ll get this:
-4x<99

Then divide both sides by -4 and flip the inequality sign

x>- 99/4

Your answer would be:

x>- 99/4

Hope this helps! :3
