Question

6x +3y = 6xy , 2x +4y = 5xy . .. Find x Nd y​

Answer 1

Answer:

6x+3y=6xy ; 2x+4y=5xy

⇒ Divide by 3xy ⇒; Divide by xy

⇒y=2

x=1,y=2 is the solution.

Answer 2

Answer:

x =1  and  y=2

Step-by-step explanation:

6x + 3 y = 6xy  --- equation 1

2x + 4 y=  5xy  ---- equation 2

Multiply eqn 2 by 3 for tallying

6 x + 3 y = 6xy

6x  + 12y=15xy   (Subtract)

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

     - 9 y = - 9xy   (cancel -9 and y on both the sides)

          1  = x

Substitute x=1 in eqn 1  

6X 1  + 3y = 6X1 x y

6 +3y=6y

6= 6y-3y

6=3y

y=6/3

y=2
