let's call the second number mentioned in the problem "x"
now let's find what the first number mentioned is compared to x. it is three more than three times x, so it is "3x+3"
the sum of the two numbers is negative five, so we can see: "x + 3x + 3 = -5"
Simplify: "4x + 3 = -5"
Solve: "4x = -8, x = -2"
Since we need to find the original number, which is 3x + 3, we can plug in -2 for x and get 3(-2) + 3 = -6 + 3 = -3.
So the answer is -3.
Hope this helps!
