–2/5x – 9

Question

–2/5x – 9 < 9/10

lacypennelll · Answer

-2/5x-9<9/10 add 9 to both sides -2/5x<99/10 Divide both sides by -2/5 Two main things happen here. remember that dividing by a fraction is the same as multiplying by its recip, and that when you multiply by a negative number, it reverses inequality signs So x>(99/10)*(-5/2) Or x> -495/20 or -99/5 unless im mistaken, x>-99/5

hero · Answer

I understand these. I'm a math major, but the way you post it can be interpreted in different ways.

hero · Answer

For example, the x could theoretically be interpreted as being in the denominator or the numerator.

Also, someone else could interpret the fraction on the left to be $$-\frac{2}{5x - 9}$$
