If two is added to both tge numerator and the denominator of a fractio...
Given:
Let the fraction be represented as x/y.

Adding 2 to both the numerator and the denominator:
(x + 2)/(y + 2) = 3/4

Subtracting 3 from both the numerator and the denominator:
(x - 3)/(y - 3) = 2/3

Approach:
To solve this problem, we will use the method of simultaneous equations. We will solve the given equations to find the values of x and y.

Solution:

Step 1: Simplify the equations

(x + 2)/(y + 2) = 3/4
Cross-multiplying, we get:
4(x + 2) = 3(y + 2)

(x - 3)/(y - 3) = 2/3
Cross-multiplying, we get:
3(x - 3) = 2(y - 3)

Step 2: Expand and simplify the equations

4x + 8 = 3y + 6 ...(1)
3x - 9 = 2y - 6 ...(2)

Step 3: Rearrange the equations

4x - 3y = -2 ...(3)
3x - 2y = 3 ...(4)

Step 4: Multiply equation (3) by 2 and equation (4) by 3 to eliminate the y term

8x - 6y = -4 ...(5)
9x - 6y = 9 ...(6)

Step 5: Subtract equation (5) from equation (6)

9x - 8x = 9 - (-4)
x = 13

Step 6: Substitute the value of x in equation (3)

4(13) - 3y = -2
52 - 3y = -2
-3y = -54
y = 18

Step 7: Verify the solution

Substituting the values of x and y in the original equations:

(x + 2)/(y + 2) = 3/4
(13 + 2)/(18 + 2) = 3/4
15/20 = 3/4
3/4 = 3/4

(x - 3)/(y - 3) = 2/3
(13 - 3)/(18 - 3) = 2/3
10/15 = 2/3
2/3 = 2/3

Hence, the value of the fraction is 13/18.
