How many solution(s) of the equation 2x + 1 = x – 3 are there on the Cartesian plane?
Answer:
Infinite solutions
Solution:
The given equation is
2x + 1 = x – 3
2x – x = – 3 – 1
x = –4
Cartesian plane representation:
There are infinitely many points on line x = –4 in the Cartesian plane so there are infinite solutions.
