A) 3
B) 2
C) 0
D) \[-2\]
Correct Answer: D
Solution :
\[\frac{2x-3y+1}{2}=\frac{x+4y+8}{3}\] \[\Rightarrow \,\,6x-9y+3=2x+8y+16\] \[\Rightarrow \,\,4x-17y=13\] ??.(i) Also, \[\Rightarrow \,\,\frac{2x-3y+1}{2}=\frac{4x-7y+2}{5}\] \[\Rightarrow \,\,\,2x-y=-1\] ??.(ii) On solving (i) and (ii), we have \[x=-1\] and \[y=-1\] \[\Rightarrow \,\,x+y=\]You need to login to perform this action.
