Question

Solve and check your answer. 

2/ 1-x = 5/ 1+x

tkhunny · Answer

First, write it correctly.  2/(1-x) = 5/(1+x) maybe?

anonymous · Answer

That is how the instructor wrote it. =l

anonymous · Answer

2/ 1-x = 5/ 1+x 
cross multiplication we get;
2(1+x)=5(1-x)
2x+2=5-5x
2x+5x=5-2
7x=3
x=3/7
on checking:
put x=3/7 on above equation u get;
2/1-(3/7)=5/1+(3/7)
7/2=7/2 which is true..
therefore x=3/7 is the reqd answer..

@PECKCE  "That is how the instructor wrote it. =l "

I sincerely hope not.  Was the instructir writing in an on-line environment?

If this is the case, then this is your big chance to correct the instructor who seems  to have forgotten the Order of Operations.

Those parentheses are NOT optional.
