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):
-9=-2k then i divide each side by -2?
OpenStudy (anonymous):
no wait. how did you get the -9
OpenStudy (anonymous):

OpenStudy (anonymous):
