Show every step no matter how small
OpenStudy (anonymous):
Ok I think that u would distribute first
OpenStudy (fibonaccichick666):
good and what do you get?
OpenStudy (anonymous):
24-16x=x-11x
OpenStudy (fibonaccichick666):
good, so next

I think add 11x
OpenStudy (fibonaccichick666):
show me?
OpenStudy (anonymous):
16x+11x
OpenStudy (fibonaccichick666):
Stop, that's the spot
OpenStudy (fibonaccichick666):
you have : \[24-16x=x-11x\]\[24-16x+11x=x-11x+11x\]
Can you simplify that?

No????
OpenStudy (fibonaccichick666):
Where is the confusion?
OpenStudy (anonymous):
Ok so u can't simplify it u would have to subtract 11x from 16x
OpenStudy (fibonaccichick666):
you can simplify it, and you add because 11x is positive
OpenStudy (anonymous):
Ok that's what I thought then u would get 27x

no, is it -16x or 16x
OpenStudy (anonymous):
Ok yeah then u would get 24=6x
OpenStudy (fibonaccichick666):
uhm... no
OpenStudy (fibonaccichick666):
ex. 4x+5x=9x
4x-5x=-x
-4x+5x=x
OpenStudy (anonymous):
Yeah if you subtract. 16x from both sides instead of 11x

no... you just do what I wrote
OpenStudy (fibonaccichick666):
\[24−16x+11x=x−11x+11x\]
Simplify this using the above ex.
OpenStudy (anonymous):
24-27x=x
OpenStudy (fibonaccichick666):
how are you getting -27?
