Question

Solve the equation 2x+1=x-3 and represent the solution:-
1. The number line.
2. The cortesion plan.​

Answer 1

Answer:

2x+1=x-3

then

2x-x =-3-1

x = -4

Answer 2

Answer:

Number line is one variable

in one variable, there is only x-axis (no y-axis)

solving 2x+1=x-3

2x-x=-3-1

x= -4

Here, 2x+1 =x-3 is a point

hence we can say that

in one variable 2x+1= x-3 is a point
