Technically is can be anything you want it to be since you did not equate this expression to any value.
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
An equation where c = 5
p+c=r.
A quadratic equation.
no

An equation where c = 5
An equation where c = -86
c is the speed of light in vacuum.
p+c=r.
A quadratic equation.
no
c = the speed of light.
The letter 'c' in that equation represents the speed of light.
That is the standard equation to graph a line.
C = speed of light
You would do it it by oppisites. 3+2+4=9 which equals C.
