-x+3>7 -x>4 x<-4 I'm assuming u got stuck on the last step, so just remember when u divide or multiply an inequality by a negative, u have to switch the direction of the sign.

OpenStudy (anonymous):

Can you please explain how you got to each step? Thank you! :)

OpenStudy (anonymous):

add \(x\) to both sides, get \[3>7+x\] then subtract 7 from both sides and get \[-4>x\]

OpenStudy (anonymous):

Is that all you have to do? That seems too easy! Thank you so much @satellite73

OpenStudy (anonymous):

yes, that is all you have to do two steps exactly yw

OpenStudy (anonymous):

Omg! Thank you so much! You have no idea how much you helped me! :)

OpenStudy (anonymous):

you are welcome again

OpenStudy (anonymous):

the only thing you have to be careful of is if you multiply or divide by a negative number, but you can always avoid that (as i did above) by making sure the coefficient of the variable is positive that is why i added \(x\) as the first step

OpenStudy (anonymous):

Oh ok! Thanks for letting me know that! :)

OpenStudy (texaschic101):

treat an inequality like an equation....keeping in mind, thereare a few inequality rules to learn.

OpenStudy (anonymous):

you could have started by subtracting 3 from both sides and getting \[-x>4\] but then you have do change the sign to get \(x\) so you have to change the inequality as well and get \(x<-4\)

OpenStudy (anonymous):

but at the risk of repeating myself, you can avoid that by adding to make sure the coefficient of the \(x\) term is positive

Thanks again! :)
