-6(2k-1)=5(3-2k)

OpenStudy (nottim):

Have you done any work on this? IF so, please show.

OpenStudy (nottim):

Cmon! Quickly now. I need to watch Batman.

OpenStudy (anonymous):

no i couldnt figure out were to start

OpenStudy (nottim):

ok.

OpenStudy (anonymous):

would you be able to help me

OpenStudy (anonymous):

simplify the left side, and the right side each on their own by multiplying the -6 with each term in the brackets, and same for the 5.

OpenStudy (anonymous):

can you do that?

OpenStudy (anonymous):

so -6 can be multiplied by 2k?

OpenStudy (anonymous):

yes and by -1

OpenStudy (anonymous):

so it will be -12k+6=..? what is the right side, do it on your own

OpenStudy (anonymous):

so on the left i should get (-12k+6)

OpenStudy (anonymous):

yes, now do the right side.. what do you get?

OpenStudy (anonymous):

(15-10k)?

OpenStudy (anonymous):

yes so the whole expression becomes -12+6=15-10k

OpenStudy (anonymous):

what do you think you can do now?

OpenStudy (anonymous):

is there still a k on the -12

OpenStudy (anonymous):

lol, yes there is my bad.

OpenStudy (anonymous):

i should try and get all the symbols on one side

OpenStudy (anonymous):

yes, and the numbers on the other side

OpenStudy (anonymous):

and all the regular numbers on the other

OpenStudy (anonymous):

yes, do that please.

OpenStudy (anonymous):

so would i add -12k to both sides

OpenStudy (anonymous):

i mean 12k

OpenStudy (anonymous):

no you wanna add +12k to each side

OpenStudy (anonymous):

yes.. and -15 to each side

OpenStudy (anonymous):

so what will you get?

OpenStudy (anonymous):

-9=-2k then i divide each side by -2?

OpenStudy (anonymous):

no wait. how did you get the -9

OpenStudy (anonymous):

sorry I mean the -9 is right, but the -2k is wrong.

OpenStudy (anonymous):

i did -10k+12k

OpenStudy (anonymous):

which is?

OpenStudy (anonymous):

-2k

OpenStudy (anonymous):

no that is +2k

OpenStudy (anonymous):

12-10=2

OpenStudy (anonymous):

sorry 2k

OpenStudy (anonymous):

so now you have 2k=9

OpenStudy (anonymous):

2k=-9 sorry

OpenStudy (anonymous):

and then, k=-9/2 which is = -4.5

OpenStudy (anonymous):

yes...thansk could you help me with a few more?

OpenStudy (anonymous):

lol sorry I gotta go study, I think you get the hang of it. But, if I have more time I will come back later. : ) Goodluck!

OpenStudy (anonymous):
