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