Question

solve by elimination method, 2(3x-y)=5xy,2(x+3y)=5xy

Answer 1

And the answer here is x =2and y= 1

Answer 2

Answer:

x=2 and y=1

Step-by-step explanation:

The given equations are:

2(3x-y)=5xy and 2(x+3y)=5xy, thus on solving, we get

6x-2y=5xy                                      (1)

2x+6y=5xy                                     (2)

Multiply equation (1) with 2 and (2) with 6 and then subtracting, we get

12x-4y-12x-36y=10xy-30xy

-40y=-20xy

x=2

Substitute the value of x=2 in equation (1),.we get

6(2)-2y=5(2)y

12-2y=10y

12=12y

y=1

Thus, x=2 and y=1
