Answer:

  • 13 tigers
  • 9 ostriches

Step-by-step explanation:

Let t represent the number of tigers. Then the number of feet is ...

  4t +2(22 -t) = 70

  2t = 26 . . . . . . . . . subtract 44, collect terms

  t = 13 . . . . . . . divide by 2; number of tigers

  22 -t = 9 . . . . number of ostriches

The zoo has 13 tigers and 9 ostriches.
