Question

Solve for x and y: x + y = 5xy, 3x + 2y = 13xy

Answer 1

First,
_________________
solution are (x,y)=(0,0)
_________________

second,

now dividing both equation by xy
and multiply than adding we get,
the above mention result show in image

now supposing 1/x=a and 1/y=b

than by elimination method we will get another solution

a+b=5
2a+5b=13

b=1
1/y=1
y=1

so,
x=1/4

Answer 2

Step-by-step explanation:

First,

_________________

solution are (x,y)=(0,0)

second,

now dividing both equation by xy

and multiply than adding we get,

the above mention result show in image

now supposing 1/x=a and 1/y=b

than by elimination method we will get another solution

a+b=5

2a+5b=13

b=1

1/y=1

y=1

so,

x=1/4
