Step-by-step explanation:
ok let's consider numerator as x
and denominator becoms y
according to given condition
y = x+2
x-y= -2..........(1)
according to second condition,
x+1/y+1 = 2/3
therefore,
3(x+1) = 2(y+1).........(cross multiply)
3x+3 = 2y+2
therefore,
3x-2y = 2-3
3x-2y = -1............(2)
now we have got 2 simultaneous equations
multiplying (1) by 2 we get
2x-2y = -4.............(3)
subtracting (3) from (2)
3x-2y = -1
-(2x-2y)= -4
3x-2y = -1
-2x+2y= 4
_________
x=3
substituting x=3 in equation 1, we get
3-y = -2
-y = -2-3
-y = -5
y = 5
hope it helps you
