=x+2+3/x+3=2/3
=x+5/x+3 =2/3
=(x+5)3 =(x+3)2
=3x+15 =2x+6
=3x-2x =6-15
= x =-9
Original fraction =-9+2/-9
=-7/-9
=7/9
=x+5/x+3 =2/3

Fraction is
Let the numerator be x and denominator be y.
According to the first condition
2x=y+2
2x-y=2...(1)
According to the second condition
Multiply equation (1) by 2
4x-2y=4...(3)
Subtract equation (2) from equation (3), we get
4x-2y=4
-
3x-2y=-3
x=7
Substituting x=7 in equation (1), we get
2(7)-y=2
14-y=2
-y=4-14
-2y=-12
y=12
