Here \: is \: the \: answer \: of \: your \: question

`\textbf{We have to find Fraction}`

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

`\textbf{Answer}`

`\textbf{a/b = 7/12}`
