What is the value of x in the equation x/5 = 3?

To solve the equation x/5 = 3, you need to isolate the variable x. This can be done by performing the reverse operation of division, which is multiplication. To eliminate the fraction, multiply both sides of the equation by 5:

(x/5) * 5 = 3 * 5

This simplifies to:

x = 15

Therefore, the value of x is 15. This confirms that the correct choice is indeed the one that indicates x equals 15. The process of multiplying both sides by the same number helps maintain the equality of the equation while isolating the variable.
