Yes, of course. In this sense, it is a number just like any number. In general, an equation can have zero, one, or several solutions; the solutions can be positive, negative, zero, fractional, irrational, or complex, depending on the equation.
Here is an equation that has zero as its solution:
x = 0 (this is only an equality if your replace "x" with 0).
Here are less trivial examples:
x + 1 = 1 (the only solution is x = 0)
x2 - x = 0 (two solutions: 0, and 1)

r=0 is the solution...
An equation that is simplified to 0 0 is called a perfect equation. It usually have exactly one solution.
The equation 3m - 3m - 7 = 0, simplifies to -7 = 0 this means that the the solution is no solution, since -7 doesn't equal 0.
Only a linear equation in one variable x , which is an equation of the form ax + b = 0, (where a is different than 0), has only one solution. The solution is: x = -b/a
Here is an example: x + 5 = 5If you subtract five from both sides, you get x = 0, which is an example of getting 0 as a solution for an equation.
