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

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! :)
