- solution:
x+2/y+1 =1 i.e, x-y+1=0;--------(1)
x+4/y+2 =1/2 i.e., 2x-y+6=0;---------(2)
solving 1 and 2...we get x= -5 and y= -4

- let numerator=x and denominator=y
according to question,
(x+2)/(y+1)=1
=>x+2=y+1
=>x-y= -1....................................(eq 1)
and
(x+2+4)/(y+1+2)=1/2
=>(x+6)/(y+3)=1/2
=>2x+12=y+3
=>2x-y= -9..................................(eq2)
solving equation 1&2,we get
x= -8 & y= -7
so fraction is
-8/-7 =8/7.............answer..:)

- x+2/y+1=1
x+2=y+1
x-y=-1
so, the ans is -8/-7
x-y=-1
-8+7=-1
thats y ans is -8/-7...

- 8/7 is the answer

- let numerator=x and denominator=y
so (x+2/y+1)=1 ie
x-y+1=0 ------(1)
and again add 4 and 2 in numerator and denominator
2x-y+9=0 ------(2)
and by solving 1 and 2 eqation we get ,
x/y=8/7 - 9 years agoHelpfull: Yes(4) No(2)
- ans is -5/-4

- X+2/y+1=1,x+2+4/y+1+2=1/2,,,,
By solving x=-8,y=-7,
So fraction =8/7 - 9 years agoHelpfull: Yes(3) No(2)
- Ansis 8/7

- x+2/y+1 = 1;
x+2=y+1
x-y=-1;
x+4/y+2=1/2;
2x+8=y+2;
2x-y= -6;
solve it
x=5, y= 6 - 10 years agoHelpfull: Yes(2) No(6)
- ans is 8/7

- n+2/d+1=1 =>n+1=d
n+1/d+2=1/2 =>d=2n+6
so n+1=2n+6 =>n=-5
and substituting the values of n d=-4
so n/d=5/4 - 9 years agoHelpfull: Yes(1) No(0)
- eq formed will be,x-y=-1
2x-y=-6
solving we get,x/y=5/4 - 8 years agoHelpfull: Yes(1) No(0)
- ans= 8/4..

- which answer r correct between in both solution 8/7 or 5/4 ...tell me plz
- 9 years agoHelpfull: Yes(0) No(0)
- -8/-7
Let numerator be x and denominator be y
2x+12=y+3
x+2=y+1
Solving this we get x=-8 and y=-7 - 7 years agoHelpfull: Yes(0) No(1)
- answer is -8/-7
((-8+2)/(-7+1))=1
((-8+6)/(-7+3))=1/2 - 7 years agoHelpfull: Yes(0) No(0)
