Question

x+y=10xy, x-y=6xy solve by long form of simultaneous equation

Answer 1

Answer:

x = 2 and y = 8

Step-by-step explanation:

x + y = 10xy

Dividing eqn by 'xy'

y + x = 10

x+y=10 ..........1)

x - y = 6xy

Dividing eqn by 'xy'

y - x = 6

-x + y =6...............2)

Adding 1) and 2)

x + y =10

-x + y = 6

--------------

2y      = 16

y = 8

Put y = 8 in eqn 1)

x + y = 10

x + (8) = 10

x = 10 - 8

x = 2

Soln. is,

x = 2 and y = 8
