x=42-:3=14 or x=42/3=14

Explanation:

You didn't list the possibilities, but there is only one.

x is the number of packages of tennis balls.

To calculate the number of packages, divide the total number of tennis balls by the number of tennis balls in each package.

x=(42"tennis balls")/((3"tennis balls")/"package")

Invert the fraction and multiply.
