Solve the equation 3x+4=5x+8 and represent the solution on

(i) The Number line

(ii) The Cartesian Plane.

What do you get as the representation of the solution on the Cartesian Plane?

In Cartesian Planes, how many solutions this equation has?

Given equation is:

3x + 4 = 5x + 8

⇒ 2x = –4

or x = – 2

(i) Representation on Number line

(ii) Representation on Cartesian plane

On representation of solution on Cartesian plane, we get a straight line parallel to y – axis and this line possess infinitely many solutions.
