Question

find the solution graphically x-2y=5 and 2x-y=2​

Answer 1

EXPLANATION.

Solution Graphically.

⇒ x - 2y = 5.

⇒ 2x - y = 2.

As we know that,

From equation (1), we get.

⇒ x - 2y = 5.

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

⇒ 0 - 2y = 5.

⇒ y = -5/2.

⇒ y = -2.5.

Their Co-ordinates = (0,-2.5).

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

⇒ x - 2(0) = 5.

⇒ x - 0 = 5.

⇒ x = 5.

Their Co-ordinates = (5,0).

From equation (2), we get.

⇒ 2x - y = 2.

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

⇒ 2(0) - y = 2.

⇒ -y = 2.

⇒ y = -2.

Their Co-ordinates = (0,-2).

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

⇒ 2x - (0) = 2.

⇒ 2x = 2.

⇒ x = 1.

Their Co-ordinates = (1,0).

Both curves intersects at a point = (-0.333, -2.667).
