Nnesha (nnesha):

@coffee789 are you sure it's (8x+7x) >???

OpenStudy (anonymous):

@Nnesha thats what im trying to figure out

OpenStudy (anonymous):

yes im sure

OpenStudy (anonymous):

8x+7x=15x

Nnesha (nnesha):

alright then first combine like terms 8x+7x= ?

OpenStudy (anonymous):

yea and you get 15x

OpenStudy (anonymous):

wouldnt it be 15x(4x3−5x2−6x+1)

OpenStudy (anonymous):

Then you subtract -6x from 15x

OpenStudy (anonymous):

That's how you get 9x

Nnesha (nnesha):

|dw:1442333350297:dw| multiply all terms by 15xx
