Question

Solve the pair of equations: 2∕x + 3/y = 13 5/x -5/y = -12​

Answer 1

Step-by-step explanation:

let 1/x= a. 1/y= b

therefore the equations will be

2a+3b=13

5a-5b=-12

10a+15b=65. (1)

10a-10b=-24. (2)

by elimination method

25b=89

b=89/25

2a+3×89/25=13

2a+267/25=13

2a=58/25

a=58/50

1/x=a

1/x= 58/50

x= 50/58

1/y=b

1/y=89/25

y=25/89

Answer 2

Answer:

x=28/29 , y=25/89
