EXPLANATION.

⇒ x - 2y = 0. - - - - - (1).

⇒ 3x + 4y = 20. - - - - - (2).

As we know that,

From equation (1), we get.

⇒ x - 2y = 0. - - - - - (1).

Put the value of x = 0 in equation, we get.

⇒ (0) - 2y = 0.

⇒ - 2y = 0.

⇒ y = 0.

Their Co-ordinates = (0,0).

Put the value of y = 0 in equation, we get.

⇒ x - 2(0) = 0.

⇒ x = 0.

Their Co-ordinates = (0,0).

From equation (2), we get.

⇒ 3x + 4y = 20. - - - - - (2).

Put the value of x = 0 in equation, we get.

⇒ 3(0) + 4y = 20.

⇒ 4y = 20.

⇒ y = 5.

Their Co-ordinates = (0,5).

Put the value of y = 0 in equation, we get.

⇒ 3x + 4(0) = 20.

⇒ 3x = 20.

⇒ x = 20/3.

⇒ x = 6.66.

Their Co-ordinates = (6.66,0).

Both curves intersects at point = (4,2).
