Let fraction be a/b
Now, according to question;
2a = b + 2
2a - b = 2 .......(1)
Also,
a + 3 = 2
________
b + 3 = 3
Now, cross multiply them
3 (a + 3) = 2 (b + 3)
3a + 9 = 2b + 6
3a - 2b = 6 - 9
3a - 2b = - 3 ..........(2)
Now multiple (1) by 2
4a - 2b = 4 .......(3)
Now, solve both (2) and (3) by elimination
+ 3a - 2b = - 3
+ 4a - 2b = + 4 (change signs)
_____________
- a - 0b = - 7
_____________
a = 7
Put value of a in (1)
2 (7) - b = 2
14 - b = 2
- b = 2 - 14
- b = - 12
b = + 12
