radar · Answer

7-9x-x-12<=25
-10x<=25+5
-10x<=30
x>=-3

Don't forget when a division or multiplication by a negative  you reverse the sense of the equality sign (direction)

radar · Answer

That is why it is the first one.  It should be noted that the first one and the third one express the same thing.  x is equal to or larger than -3 !!
