Answer: 9 elm trees were removed.

Step-by-step explanation:

Let x represent the number of elm trees removed.

The total number of elm trees in the park is 22. Elm leaf beetles have been attacking the trees. After removing several of the diseased trees, there are 13 healthy elm trees left. The equation to find the number of elm trees that were removed would be

x + 13 = 22

Subtracting 13 from the left hand side and the right hand side of the equation, it becomes

x + 13 - 13 = 22 - 13

x = 9
