OpenStudy (x3_drummerchick):

for # 2, solve for x individually for each equation

OpenStudy (x3_drummerchick):

3(2x-4)=-18 6x - 12 = -18 6x = -18 + 12 6x = 6 x=1 6x - 12 = -18 6x = -18 + 12 6x = 6 x=1 yes they are equivalent

OpenStudy (anonymous):

So they're equivalent by the associative property right?

OpenStudy (x3_drummerchick):

i would say yes

OpenStudy (x3_drummerchick):

\[\frac{ 3-2^{2} }{ 3 -2 }\]

OpenStudy (anonymous):

OK and what about four, I keep getting -1/3

OpenStudy (x3_drummerchick):

\[\frac{ 3-4 }{ 1 }\]

OpenStudy (x3_drummerchick):

\[\frac{ -1 }{ 1 } = 1\]

OpenStudy (x3_drummerchick):

that is for number 4 ^

OpenStudy (x3_drummerchick):

i think you multiplied in the denominator instead of subtracting

OpenStudy (x3_drummerchick):

does that make sense?

OpenStudy (anonymous):

Oh ok, thanks! :)

OpenStudy (x3_drummerchick):

wait its -1 ! not +1, that was a typo

OpenStudy (anonymous):

Oh LOL I was like what??? Thanks!

OpenStudy (x3_drummerchick):

no problem :)
