The goal is to isolate 'x'. If you apply an operation to both sides of an equation, it does not change the equality. If you multiply both sides of the equation by 3/2, then the 2/3 on the left-side will cancel leaving the following:

When multiplying fractions, you simply multiply through and through. Therefore the above equation becomes:

The fraction can be simplified by dividing the top and bottom by 6, to get

Answer:
B
Step-by-step explanation:
It helps if you have the figure included. However, since it is not, we can assume that she has gone around the circle with all six sides of the hexagon is set to PR.
That makes the hexagon with 6 equal sides. It also makes each triangle using one of the sides equal to PR. The radii are all equal. There are 6 triangles making up the hexagon.
Both statements she makes are true and that makes B the answer.
