I assume that you use:

1. Equation of the plane

2. Distance of the point to the plane is:

If so:

Multiply the equation by the common denominator (here it is 12) to get rid of the fractions, expand the brackets and collect the constants. You have now an equation in the well known form:

3.

4. Go ahead!
