Answer:

8

Step-by-step explanation:

Say the number of rabbits is r, we can write the rabbits, horses, and hamsters in terms of r:

  • Rabbits: r
  • Horses: r-7
  • Hamsters: 3r

So the total amount of pets is r+(r-7)+3r=33:

  • r+(r-7)+3r=33
  • Remove parenthesis, r+r-7+3r=33
  • Combine like terms, 5r-7=33
  • Add, 5r=40
  • Divide, r=8

Check your work:

  • Rabbits: 8
  • Horses: 8-7=1
  • Hamsters: 3(8)=24
  • Total: 8+1+24=33
