The second number is nine less than the first number.

The sum of the first number and the second number is negative twenty-seven.

02

Step 2. Solution 

Consider the first number is n

One number is nine less than another.

so the second number is n-9

The sum of the first number and the second number is -27

localid="1647199414829" n+(n-9)=-272n-9=-272n=-18n=-9

So the first number is-9

The second number is

localid="1647199448374" n-9=-9-9=-18

So numbers arelocalid="1647199467873" -9&-18.

Step 3. Verification  

-18is 9less than -9.

-18=-9-9-18=-18
