x-3/x=0

To solve the equation \(\frac{x - 3}{x} = 0\), you can start by setting the numerator equal to zero, since a fraction is zero only when its numerator is zero (assuming the denominator is not zero).

1. Set the numerator equal to zero:
   \[ x - 3 = 0 \]

2. Solve for \(x\):
   \[ x = 3 \]

Next, check if this value makes the denominator zero:

• The denominator is \(x\), and if \(x = 3\), the denominator is not zero.

Thus, the solution to the equation \(\frac{x - 3}{x} = 0\) is: \[ \boxed{3} \]
