Question 711275
{{{5x-9>9x+9}}}
Add -9x to each side:
{{{-9x+5x-9>9}}}
Combine the x terms:
{{{-4x-9>9}}}
Add 9 to each side:
{{{-4x>18}}}
Divide each side by -4. You need to swap the inequality direction anytime you multiply/divide each side by a negative number:
{{{x<(-18/4)}}}
Simplify and you are done:
{{{highlight(x<(-9/2))}}}
