Answer:

y=2,x=3

Step-by-step explanation:

xy=6y-6

put value of xy in equation 2

you'll get y =2

and put y=2 in

eqn 1

you'll get x=3

Hbsunny: I didn't find anything please ask me here
Chitrayogee: Solve the system of equations : (a) 2x + y - 3 = 0 , 2x - 3y - 7 = 0
(b) 1/5x + 1/6y = 12 , 1/3x -3/7 y=8

Answer:

y=2 and x=3

Step-by-step explanation:

Say z = xy

Therefore given equations are

z - 6y =  - 6 \\ 3z - 5y = 8 \\ multiply \: first \: equation \: by \: 3 \\ 3z - 18y =  - 18 \\ subtract \: equation \: 2 \: from \: 3 \\  - 13y =  - 26 \\ y = 2 \\ substitute \: this \: in \: any \: of \: the \: above \: equation \: will \: give \: you \: z = 6 \\ i.e \: xy = 6 \\ but \: y = 2 \\ therefore \: x = 3
