    1 way (without equation)

    Kathy counts in total 9 goats and sheep at the petting zoo. Her brother counts 4 goats. Then if you subtract the amount of goats from the total amount, then you obtain the amount of sheep.

    9-4=5 is the number of sheep at the petting zoo.

    2 way (with equation)

    Let x be the number of sheep at the petting zoo. If brother counts 4 goats, then the total number of animals is x+4. Kathy counts in total 9 goats and sheep at the petting zoo, then x+4=9.

    Solve this equation:

    x+4-4=9-4,

    x=5.

    3 way (with equation)

    Let x be the number of sheep at the petting zoo. If total number of animals is 9, then the amount of goats can be found as 9-x. Brother counts 4 goats, then

    9-x=4,

    9-4=x,

    x=5.

    Answer: 5 sheep.

    4 + s = 9

    9 - s = 4

    These should be the two ways to solve.
