Hey there :D is there answer choices ?
OpenStudy (anonymous):
Nope.
jagr2713 (jagr2713):
Ok first we simplify 2/1 to get what?
OpenStudy (anonymous):
2
jagr2713 (jagr2713):
Goo we we have\[2=8x-\frac{ 2 }{ 9 }\] left ok now what do we do next?

Oops, should have specified= \[2 = (8x - 2) / 9\]
jagr2713 (jagr2713):
nope we add 2/9 to both sides and what do we get?
jagr2713 (jagr2713):
we add on both sides 2+2/9=?
OpenStudy (anonymous):
? I'm not following.

we are tying to x by its self so we add on both sides b.c its negative
jagr2713 (jagr2713):
you get it now @hputerpop
OpenStudy (whpalmer4):
So the actual problem is \[\frac{2}{1} = \frac{8x-2}{9}\]
OpenStudy (whpalmer4):
or \[\frac{2}{1} = 8x - \frac{2}{9}\]
OpenStudy (anonymous):
Yep

Or i was doing the 2/1=8x one
jagr2713 (jagr2713):
do u understand @hputerpop
OpenStudy (whpalmer4):
Unclear which one you said "yep" to...
\[\frac{2}{1} = \frac{8x-2}{9}\]I would cross-multiply:
\[2*9 = 1*(8x-2)\]\[18=8x-2\]\[20=8x\]\[x=\]
