Step-by-step explanation:
Given Class 10 chapter 3 example 17
- Now we need to solve the given linear equations
- 2/x + 3/y = 13 ----------- 1
- 5/x – 4/y = - 2-------------2
- Now multiply equation 1 by 5 and equation 2 by 2 we get
- 10/x + 15/y = 65
- 10/x – 8/y = - 4
- Subtracting both the equations we get
- 15/y + 8/y = 69
- 23/y = 69
- Y = 23 / 69
- Y = 1/3
- Substituting the value of y in equation 1 we get
- 2/x + 3/1/3 = 13
- 2/x + 9 = 13
- 2/x = 13 – 9
- 2/x = 4
- X = 2/4
- X = ½
- So we get x = ½ , y = 1/3
