What does the line 2x + 7 = 7 look like?

The given equation is

2 x + 7 =7

There are three possibilities

1. If we consider this equation , as equation in one variable,

The Solution will be

2 x + 7 =7

2 x = 7 -7 →→→[Taking Constant on Right side of Equation]

2 x = 0

Dividing both sides of equation by 2, the given equation gives value of x

→x = 0

We can represent it on the number line , as a real value of x, which is Zero.(Shown below)

2. If we consider this equation as equation in two variable

→2 x + 0 × y + 7=7

Gives , →x=0

So, the point will be represented as Origin in two dimensional plane.

Similarly if we consider this equation as equation in three variable ,

→2 x + 0 × y + 0 × z =7

Gives , →x=0

So, the representation will be a point in three dimensional plane as (0,0,0) i.e origin having ,x coordinate as well as y and z coordinate as 0.
