Step-by-step explanation:

First of all,

=>2x+3y=0+9

=>2x+3y=9

=>5xy=9

=>xy=9/5

Second Of All,

=>4x+6y=0+18

=>4x+6y=18

Answer 2

EXPLANATION.

⇒ 2x + 3y - 9 = 0. - - - - - (1).

⇒ 4x + 6y - 18 = 0. - - - - - (2).

As we know that,

From equation (1) & (2), we get.

Multiply equation (1) by 2.

Multiply equation (2) by 1.

⇒ 2x + 3y - 9 = 0. - - - - - (1) x 2.

⇒ 4x + 6y - 18 = 0. - - - - - (2) x 1.

We get,

⇒ 4x + 6y - 18 = 0. - - - - - (3).

⇒ 4x + 6y - 18 = 0. - - - - - (4).

Subtract the equation, we get.

⇒ x = 0 & y = 0.
