~*~*~*~ HELP PLEASE ~*~*~*~ show work pleasee. problem posted below

OpenStudy (anonymous):

\[\frac{ 4 }{ 6x+9 }-\frac{ 2 }{ 3 }=\frac{ 5 }{ 18x+27 }\]

OpenStudy (anonymous):

Howwwww abouttt, i tell you how to do it Step 1, make all denominators equal Step 2, solve like a normal equation

OpenStudy (anonymous):

okay so would the common denominator be 18x+27

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

i got 12x+12-36x=5 is that right

OpenStudy (anonymous):

Not what I got

OpenStudy (anonymous):

once you made your denominators different did you cancel them all out?

OpenStudy (anonymous):

idk what i did then

OpenStudy (anonymous):

i mean denominators THE SAME sorry...

OpenStudy (anonymous):

i multiplied each section by the common denominator then like divided and stuff. idk

OpenStudy (anonymous):

\[(4/6x+9) - (2/3) = (5/18+27)\]

OpenStudy (anonymous):

make denominators the same by... Multiplying the numerator and the denominator of the FIRST fraction by 3 Multiplying the numerator and denominator of the SECOND fraction by (6x+9) And leaving the last fraction alone

OpenStudy (anonymous):

Then, cancel out your denominators from everything and strictly work with the numerators like 2 step equation you learned in grade school

OpenStudy (anonymous):

i hope that helped a little

|dw:1410112102264:dw| thats what i did
