OpenStudy (anonymous):

can you simplify (x-8y)-(2x-4y)

OpenStudy (lgbasallote):

x - 8y - 2x + 4y

OpenStudy (lgbasallote):

now combine

OpenStudy (anonymous):

-2x-4y?

OpenStudy (lgbasallote):

not exactly...but close...you got the y part right BUT x - 2x is NOT -2x

OpenStudy (anonymous):

-3x?

OpenStudy (lgbasallote):

x - 2x is like 1 - 2

OpenStudy (anonymous):

-1x

OpenStudy (lgbasallote):

-1x is traditionally written as -x so the answer overall is -x - 4y
