The given information gives both Marcia's and Ann's numbers of points compared to Judy's, so use Judy's number of points for the variable:

x = Judy's points
x-3 = Marcia's points (3 less than Judy)
2x = Ann's points (twice as many as Judy)

Write and solve the equation that says the total number of points was 45.
