Question

When you are solving an inequalities when should you change the greater or less than sign is it when the x is negative?

like -2x>1 should the answer be x<-1/2 ?
or 2x>-1 is x<-1/2
i think the second one is wrong

Answer 1

yes u r correct

Answer 2

if you multiply or divide by a negative number, the inequality symbol changes direction. If the question is -2x>1 then divide by -2 and get x<-1/2. If the question is 2x>-1, then divide by 2 and get x>-1/2

Answer 3

inequality reverses if we multiply with a negative no
