Question

-2/5x - 9 < 9/10

Answer 1

first add 9 to both sides
\[\frac{ -2 }{ 5 }x < 9/10 + 9/1\]
make the LCD 10
\[\frac{ -2 }{ 5x } < 9/10 + 90/10\]
combine the fraction for 99/10 then multiply each side by 5
\[-2x < \frac{ 99 }{ 10 } * \frac{ 5 }{ 1 }\]
then it becomes 99/2\[-2x < 99/2\]
divide each side by -2 and your answer is?
