An independent variable is something which you can change, like the temperature of a body (by heating or cooling). A dependent variable is the property of the body that changes when something changes. Like in this case, the volume of the body, its electrical resistance etc.
A constant variable cannot exist. If something is constant, it is no longer a variable.

I'm guessing this is it
independent variables => 2x + 3y
x & y can be anything
dependent variables => 2x + 3y = 5
x = 1& y=1 OR x=2.5 & y=0 OR etc
constant variables => 3x = 12
=> x = 4 only

an independent variable is a value that does not depend on another variable.on a graph it will be the value along the x axis.
an dependent variable is a value that depends on another variable.on a graph it will be the value along the y axis.(value of y depends on the value of x)
constant variable is a value that does not change.
