Step-by-step explanation:

3x+14y=5xy.....(1)

21y-x=2xy

= -x+21y =2xy.... (2)

multiplying equation 1 by 21 and equation 2by 14,we got...

63x+294y=105xy....(3)

-14x+294y=28xy...(4)

solving the two equation 3and 4, we got that..

= y =1

then put the value y=1 In equalation 1

3x+14y=5xy

= 3x+14=5x

= 5x-3x=14
