start by multiplying each side by 3 to get rid of the denominator

yes, so you should get 24 -6b=2(12b+6)
OpenStudy (gorv):
\[3*(3-2b)=3*\frac{ -2 }{ 3 }(12b+6)\]
OpenStudy (gorv):
sorry that is 8-2b not 3-2b
OpenStudy (anonymous):
okay that's what I got
OpenStudy (anonymous):
and its okay haha @gorv

on right side 3 will cancel 3 agree???
OpenStudy (anonymous):
Yes.
OpenStudy (anonymous):
So after that do I add the parentheses?
OpenStudy (anonymous):
you cant add the parentheses, you need to simplify all terms then add common terms
OpenStudy (gorv):
multiply the number inside that is outside the paranthesis

so distribute the -2 through the parentheses
OpenStudy (gorv):
3*8-3*2b=-2*12b-2*6
OpenStudy (gorv):
yes do it and tell me what you u got ...??
btw you are goin right way
OpenStudy (anonymous):
24 - 6 = (-24 + -12) ?? I'm not sure if that's correct.
