Question

How many solution of equation 2x+1=x-3 are there on the
i Number line
ii, cartesian plane ​

Answer 1

Answer:

2x + 1 = x – 3

2x-x = -3-1

∴ x = – 4 ………..(i)

and it can be written as 1.x + 0. y = – 4 …………..(ii)

(i) Number line represent the all real values of x on the X-axis. Therefore, x = – 4 is exactly one point which lies on the number line.



(ii) Whereas the equation x + 4 = 0 represent a straight line parallel to Y-axis and infinitely many points lie on a line in the cartesian plane.
