i really need a good grade on this

OpenStudy (anonymous):

five plus seven n plus four minus two n is greater than four: 5+7n+4-2n>4 Are you able to solve the equation?

OpenStudy (anonymous):

no i really dontknow this stuff and my parents will kill me if i get anything but and A

OpenStudy (anonymous):

first you are going to combine like terms: 7n-2n and 5+4 So now we will have 5n+9>4 Subtract 9 from both sides: 5n>-5 Lastly divide 5 on both sides and get: n>-1

OpenStudy (anonymous):

So the answer to this one is b

OpenStudy (anonymous):

I mean A

OpenStudy (anonymous):

are you able to try the next one?
