A) \[-\frac{p+q}{b+c}\]
B) \[\frac{bq-pc}{a\,\,(b+c)}\]
C) \[\frac{bq+pc}{a\,\,(b+c)}\]
D) \[\frac{a\,\,(b+c)}{bq+pc}\]
Correct Answer: B
Solution :
By cross-multiplication method, \[\frac{x}{-\,\,bq+pc}=\frac{y}{ap+aq}=\frac{1}{-\,\,ac-ab}\] \[\Rightarrow \] \[x=\frac{-bq+pc}{-\,\,ac-ab}\] \[x=\frac{bq-pc}{a\,\,(b+c)}\]You need to login to perform this action.
