Question

3x+2y=2xy,6x+2y=3xy elimination method​

Answer 1

Answer:

(3x+2y=2xy) × 2 = 6x + 4y = 4xy --> ( i )

6x+2y=3xy --> ( ii )

Subtracting (i) from (ii),

6x + 4y - 6x - 2y = 4xy - 3xy

2y = xy

x = 2

Now putting value of x in equation ( ii),

6(2) + 2y = 3*2*y

12 + 2y = 6y

12 = 4y

y = 12/4 = 3

y = 3
