−25x−9<910-\frac{2}{5}x-9<\frac{9}{10}
1
Simplify  25x\frac{2}{5}x  to  2x5\frac{2x}{5}.
−2x5−9<910-\frac{2x}{5}-9<\frac{9}{10}

2
Add 99 to both sides.
−2x5<910+9-\frac{2x}{5}<\frac{9}{10}+9

3
Simplify  910+9\frac{9}{10}+9  to  9910\frac{99}{10}.
−2x5<9910-\frac{2x}{5}<\frac{99}{10}

4
Multiply both sides by 55.
−2x<9910×5-2x<\frac{99}{10}\times 5

5
Use this rule: ab×c=acb\frac{a}{b} \times c=\frac{ac}{b}.
−2x<99×510-2x<\frac{99\times 5}{10}

6
Simplify  99×599\times 5  to  495495.
−2x<49510-2x<\frac{495}{10}

7
Simplify  49510\frac{495}{10}  to  992\frac{99}{2}.
−2x<992-2x<\frac{99}{2}

8
Divide both sides by −2-2.
x>−9922x>-\frac{\frac{99}{2}}{2}

9
Simplify  9922\frac{\frac{99}{2}}{2}  to  992×2\frac{99}{2\times 2}.
x>−992×2x>-\frac{99}{2\times 2}

10
Simplify  2×22\times 2  to  44.
x>−994x>-\frac{99}{4}

Done
