Answer: x = 16</h2>
Step-by-step explanation: Let X stand for Australia.
2x for Russia
x for Australia
x-3 for Italy
Equation: 2x + x + x - 3 = 61
Combine: 4x - 3 = 61
Add 3: 4x = 64
Divide: x = 16
But it back: 2(16) + 16 + 16 - 3 = 61 --> 64 - 3 = <u>61</u>

So the answer is x = 16.
107-7=90
90divided 5=18
18*5=90+17=107
