<h2>Steps:</h2>
So for this, we will be setting up a system of equations with the information we have:
![x+y=13\ \textsf{"The sum of two numbers is 13."}\\2x-3y=1\ \textsf{"Two times the first number minus three times the second number is 1."}](https://tex.z-dn.net/?f=x%2By%3D13%5C%20%5Ctextsf%7B%22The%20sum%20of%20two%20numbers%20is%2013.%22%7D%5C%5C2x-3y%3D1%5C%20%5Ctextsf%7B%22Two%20times%20the%20first%20number%20minus%20three%20times%20the%20second%20number%20is%201.%22%7D)
Now we have our system of equations set up. Next, I will be using the substitution method to solve this system. So firstly, subtract y on both sides of the first equation:
![x=13-y\\2x-3y=1](https://tex.z-dn.net/?f=x%3D13-y%5C%5C2x-3y%3D1)
Now, substitute x for (13 - y) in the second equation and solve for y as such:
![2(13-y)-3y=1\\26-2y-3y=1\\26-5y=1\\-5y=-25\\y=5](https://tex.z-dn.net/?f=2%2813-y%29-3y%3D1%5C%5C26-2y-3y%3D1%5C%5C26-5y%3D1%5C%5C-5y%3D-25%5C%5Cy%3D5)
Now that we have the value of y, substitute it into either equation to solve for x:
![x+5=13\\x=8\\\\2x-3(5)=1\\2x-15=1\\2x=16\\x=8](https://tex.z-dn.net/?f=x%2B5%3D13%5C%5Cx%3D8%5C%5C%5C%5C2x-3%285%29%3D1%5C%5C2x-15%3D1%5C%5C2x%3D16%5C%5Cx%3D8)
<h2>Answer:</h2>
<u>In short, the first number (x) is 8 and the second number (y) is 5.</u>
Answer:
No because to you have gotten heads one out of the three times so it would probably take 6 tries to get heads again.
