First, write the value(s) that make the denominator(s) zero. Then solve the equation. 7 over x +9 = 5 over 2x +10 over 3
Destinyyyy
  • Destinyyyy
I got x= -27 over 34

\[\frac{ 7 }{ x+9 }=\frac{ 5 }{ 2x+\frac{ 10 }{ 3 } }\] is dat the original eqn?

Ah thank you @Destinyyyy so first part of the Q asks for value(s) that makes the denominator(s) zero, wat have u got?
Destinyyyy
  • Destinyyyy
I have x= -27 over 34 and x=/ 0
superdavesuper
  • superdavesuper
x=0 will make denominator equal to 0 for sure :) how u get x=-27 will do the same?
Destinyyyy
  • Destinyyyy
Um I multiplied all of it by 6x to get rid of the fractions?
superdavesuper
  • superdavesuper
|dw:1449173759673:dw| so far so good?
Destinyyyy
  • Destinyyyy
Um yeah?
Destinyyyy
  • Destinyyyy
Are you saying my answer is wrong?
superdavesuper
  • superdavesuper
No, what im saying is x=0 is what will make denominator zero. The other calculation u did actually solves the problem n give u the solution instead :)
Destinyyyy
  • Destinyyyy
Thats what im supposed to do.

  • Destinyyyy
Yes that what I have written down. So my answer is correct. You could have just said its correct.
superdavesuper
  • superdavesuper
Ah sorry I mis-understood and thought u were saying x=-27/34 will make denominator zero. Sorry again!
Destinyyyy
  • Destinyyyy
Nope.. Its okay.
Destinyyyy
  • Destinyyyy
Next question..
Destinyyyy
  • Destinyyyy
Solve nd check the equation |dw:1449174337521:dw|
Destinyyyy
  • Destinyyyy
Solve and **
superdavesuper
  • superdavesuper
u got the ans on tis n just want me to check or need help?
Destinyyyy
  • Destinyyyy
I actually need help on this one. I dont remember how to solve it.
superdavesuper
  • superdavesuper
|dw:1449174445437:dw| good so far?
Destinyyyy
  • Destinyyyy
Yes.
superdavesuper
  • superdavesuper
|dw:1449174632653:dw| ok?
Destinyyyy
  • Destinyyyy
Yeah.. But I dont remember ever doing that.. I remember something about flipping. Like 7/2 to 2/7
Destinyyyy
  • Destinyyyy
Hmm maybe Im wrong.
superdavesuper
  • superdavesuper
sorry flipping the exponent does not make any sense period. i deleted my last post cuz' its not even 1/4. OK want to continue as it is now @Destinyyyy ?
Destinyyyy
  • Destinyyyy
Yes please
superdavesuper
  • superdavesuper
|dw:1449175131423:dw|
Destinyyyy
  • Destinyyyy
Yep im at x^7 =16
superdavesuper
  • superdavesuper
n the new stuff i wrote at the top - u get 'em? :)
Destinyyyy
  • Destinyyyy
So the answer is 2^ 4/7 ?
Destinyyyy
  • Destinyyyy
I dont have that as an option..
superdavesuper
  • superdavesuper
:( double-check the original eqn....see if i mis-read anything...n post the choices plz?
