Answer and explanation:
If the sum of the three numbers equal -46 then write an equation for it.
24 + x + x = -46
Since it's three numbers and two of them are equal, you just write the same letter for it (you can choose whichever one you want).
Work out the equation written to get the other two numbers
24 + x + x = -46
24 + 2x = -46 Add the two x's together
-24 -24 Subtract 24 from both sides to cancel it out and leave 2x alone
2x = -72 Divide by 2
So the three numbers would be 24, -36, and -36
24 + (-36) + (-36)
24 + (-72)
-46
