What is the value of x in the equation 3xy = 18 when y = 27?

To find the value of x in the equation 3xy = 18 when y = 27, we can begin by substituting the value of y into the equation.

So, substituting y = 27 in the equation:

3x(27) = 18

This simplifies to:

81x = 18

Next, we need to isolate x. We do this by dividing both sides of the equation by 81:

x = 18 / 81

This can be simplified further:

x = 2 / 9

Thus, the value of x when y = 27 in the equation 3xy = 18 is:

x = 2/9

So the solution is x = 2/9.
