The answer is A. multiply both sides by 3.

When solving an equation, we want to isolate the variable on one side by performing the inverse operation of the operation being performed on the variable.

In the given equation, the variable "x" is being divided by 3. To isolate "x," we need to perform the inverse operation, which is multiplying by 3. By multiplying both sides of the equation by 3, we maintain the equality of the equation.

Multiplying both sides by 3 gives us:
