@alexwee123 another one! haha
OpenStudy (xguardians):
Lol can you use equation instead of writing it in letters , makes it easier to follow :P?
OpenStudy (anonymous):
\[\frac{ 3 }{ 2 }-\frac{ 1 }{ x-4 }=\frac{ -2 }{ 2x-8 }?\]
OpenStudy (alexwee123):
ok do you know what common denominators are ?

do you see how you could simplify 2x-8?
OpenStudy (anonymous):
*hint look at the denominators of your other fractions*
OpenStudy (alexwee123):
ok so what do you think the common demoniator between 3/2 and 1/(1-x) is?
OpenStudy (anonymous):
\[2\left( x-4 \right) ?\]
OpenStudy (alexwee123):
sorry 1/(x-4)*

yes. now how do you change the denominators of your other fractions to get that same answer?
OpenStudy (anonymous):
This is where i'm stuck :/
OpenStudy (anonymous):
*hint you can multiply a fraction by another fraction that is equivalent to one*
OpenStudy (alexwee123):
yea awesome so if we simplify these two out we'd get
|dw:1402437759003:dw|
