Question

6 X + 3 Y is equal to 6 x y ; 2 x + 4 y is equal to 5 x y find the value of x and y​

Answer 1

6x+3y=6xy-------(1)

2x+4y=5xy-------(2)

By elimination method,

Eqn(2)*3

So,

6x+ 3y= 6xy

6x+12y= 15xy (subtract)

- - -

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

0x-9y=-9xy

y=-9/-9

y=x

Putting y=x in eqn (2)

2x+4(x)=5x(x)

6x=5x^2

x=6x/5x

x=6/5

Answer:x=6/5

y=6/5
