x is at most -5 means x cannot be >-5
$$i.e.,x \le -5$$

Solve the inequality.





5x – 7(x + 1) > –9 + 3 @petiteme and @surjithayer

petiteme · Answer

Distribut -7 first
5x-7x-7>-6
-2x-7>-6
transpose -7
-2x>1
divide both sides by -2
x>-1/2 :)

anonymous · Answer

correction
-2x>1
divide by -2
x<-1/2

anonymous · Answer

when we divide or multiply by a negative quantity  the inequality changes.
