\[6\le3-2(x-5)<14\]

OpenStudy (lgbasallote):

first.. subtract 3 from ALL sides. what do you get?

Parth (parthkohli):

Whatever you do, do the same to ALL THREE SIDES.

OpenStudy (anonymous):

\[My answer: \frac{ 13 }{ 2 }\ge x > \frac{ -7 }{2 }\]

Parth (parthkohli):

Umm... no.

OpenStudy (lgbasallote):

remember..you divide all sides by -2 later on right?

OpenStudy (anonymous):

OH I SEE WHAT I DID hold on.

OpenStudy (anonymous):

19/2 greater than or equal to x greater than or equal to 1/-2

OpenStudy (lgbasallote):

hmmm... i think you should present the solution now....

OpenStudy (lgbasallote):

the right side is right...but the left side is....left

OpenStudy (lgbasallote):

and by left i mean wrong

OpenStudy (anonymous):

Is it the number or is it the inequality it comes out to be -19/-2

OpenStudy (lgbasallote):

ok...let me help you \[6 \le 3 - 2(x-5)\] SUBTRACT 3 from both sides..what do you get?

OpenStudy (anonymous):

Oh, I forgot the 6 is suppose to be negative. So... my mistake, sorry.

OpenStudy (lgbasallote):

oh...

OpenStudy (lgbasallote):

so \[-6 \le 3 - 2(x-5) < 14\]

OpenStudy (lgbasallote):

is that the question?

OpenStudy (anonymous):

Yeah! Is it possible for the inequalities to go the same way?

OpenStudy (lgbasallote):

what do you mean same way?

OpenStudy (anonymous):

so it would be <-----1/-2====0====19/2====>

OpenStudy (lgbasallote):

do you mean the graph?

OpenStudy (anonymous):

yes.

OpenStudy (lgbasallote):

it would look like this |dw:1346920384175:dw|
