Question:-

Solve this by subtitution method x+y=5xy and 3x+2y=13xy

Solution:-

Equations are-------

1. x+y=5xy

2. 3x+2y=13xy-------------equation 2

From

➡x+y=5xy

➡x=5xy-y ---------------------- equation 1

➡Now substituting equation 1 in equation 2

so our equation is....

➡3[5xy-y]+y=5xy

➡15xy-3y+6=5xy

➡15xy-5xy=3y-y

➡10xy=2y

➡5xy=y

➡x=-5✔✔✔✔

Now by substituting value of x in ...

➡x+y=5xy

➡-5+y=5×-5×y.....

Now solving further u will get value of y
