8d-4d-6d-8 = 2d

OpenStudy (shamil98):

Combine 8d - 4d - 6d think of it as 8 - 4 - 6 then after you do then add the variable again what do you get?

OpenStudy (zale101):

You can do it jared!

OpenStudy (anonymous):

18d?

OpenStudy (shamil98):

that is addition, not subtraction

OpenStudy (anonymous):

-2d

OpenStudy (shamil98):

correct.

OpenStudy (shamil98):

-2d - 8 = 2d now you want to get the variable d and its coefficent on one side what do you do?

OpenStudy (anonymous):

add 2 to both sides of the equal sign?

OpenStudy (shamil98):

add 2d* yes

OpenStudy (shamil98):

you get -8 = 4d now the last step is to get d without its coefficient that it is multiplied to what is the opposite of multiplication?

OpenStudy (anonymous):

divide 4d on both sides

OpenStudy (shamil98):

divide 4 to both sides. not 4d so -8/4 = 4d/4 what do you get as the value of d?

OpenStudy (anonymous):

d=-2

OpenStudy (shamil98):

correct, good work
