Solve by eliminating by equations coefficient 8/x - 5/y =34 3/x - 2/y = 13 ​

Answer»

Step-by-step explanation:

8/x - 5/y = 34

3/x - 2/y = 13

let 1/x = a ; and 1/y = b

the equations will be

8a - 5b = 34. equ (1)

3a - 2b = 13 equ (2)

multiply EQUATION (1) with 2 and equation (2) with 5

16a - 10b = 68 equ (3)

15A - 10b = 65 equ (4)

subtract (3) - (4)

we get

a = 3

substitute a = 3 in equ (2)

3(3) - 2b = 13

9 - 2b = 13

-2b = 13 - 9

- 2b = 4

- b = 4/2

- b = 2

b = - 2

a = 1/x = 3

x = 1/3

b = 1/y = -2

y = - 1/2
