<table border = 1>
<tr>
<td>{{{2x=y+1}}}</td> <td>two times the first number (x) is one more than the second number (y)</td></tr>
<tr>
<td>{{{x+y=-64}}}</td> <td>their sum is -64</td>
</tr>

<tr>
<td>{{{x=-64-y}}}</td><td>Solve for x in terms of y using the second equation</td></tr>
<tr>
<td>{{{2(-64-y)=y+1}}}</td><td>Substitute x in the first equation</td></tr>
<tr><td>{{{-128-2y=y+1}}}</td></tr>
<tr><td>{{{3y=-129}}} ==> {{{y=-43}}}</td></tr>

Solve for x using y as -43, we get x=-21.
The two number are <b> -21 and -43</b>.
