i think

OpenStudy (anonymous):

x < -7

OpenStudy (anonymous):

if im not mistaken you flip the sign when you divide by a negative

Nnesha (nnesha):

\[\huge\rm -5x + 7 > 42\] first step to subtract 7 both and then divide by -5 and yes if you divide or multiply by negative number u must have to flip inequality sign
