Question

Solve 2/x+ 3/y = 13 and 5/x- 4/y =-2

Answer 1

Answer:

Step-by-step explanation:

Let 1/x =p and 1/y = q

2p+3q=13. And. 5p-4q=. -2

p=13-3q/2. Put this value in second equation

5(13-3q/2) -4q = -2

65 -15q/2 -4q= -2

Taking LCM

65-15q-8q/2= -2

65-23q= -4

69 = 23q

q = 3

Put q=3 in 13-3q/2

p = 2

Therefore

2=1/x. 3=1/y

x = 1/2. ,y=1/3

x=1/2
