-4/10x - 9 < 9/10
multiply by 10
-4x - 90 < 9
-4x < 99
x > -99/4
or
x > -24 3/4
Looks like you dropped the minus sign somewhere
Too bad you couldn't be bothered to show your work...
-4/10x -9 < 9/10 = x < 24 3/4
Did I do this right? was solving for the inequality and the -4/10x is together.

I hope your text did not print it this way. The "= x < 24 3/4" is quite confusing.
I will read it as:
(-4/10)x -9 < 9/10 AND x < 24 3/4
first part times 10
-4x - 90 < 9 and x < 99/4
-4x < 99 and x < 99/4
x > -99/4 and x < 99/4
or
-99/4 < x < 99/4
I will read it as:
(-4/10)x -9 < 9/10 AND x < 24 3/4
first part times 10
-4x - 90 < 9 and x < 99/4
-4x < 99 and x < 99/4
x > -99/4 and x < 99/4
or
-99/4 < x < 99/4
