How many solution(s) of the equation 2x + 1 = x – 3 are there on the number line?

 

 

How many solution(s) of the equation 2x + 1 = x – 3 are there on the Cartesian plane?

Answers (1)

Answer:

Only one solution

Solution:

The given equation is

2x + 1 = x – 3

2x – x = – 3 – 1

x = –4

Representation on number line:

On number line, there is only one solution

 

 

 

Answer:

Infinite solutions

Solution:

The given equation is

2x + 1 = x – 3

2x – x = – 3 – 1

x = –4
