i need help on any 3 numbers that add up to -84 and any 3 number that add up to 54
thanks
-26 + (-28) + (-30) = -84
16 + 18 + ___ = 54
oh thank you so much:)
You're welcome.
To find three numbers that add up to -84, we can start by setting up an equation. Let's call the three numbers x, y, and z. The equation can be written as:
x + y + z = -84
To find any solution, we need to choose values for x and y and then solve for z.
Let's say we choose x = 0 and y = -84. Substituting these values into the equation, we have:
0 + (-84) + z = -84
-84 + z = -84
Simplifying further, we get:
z = 0
So, one solution can be x = 0, y = -84, and z = 0.
To find another solution, we can choose different values for x and y. Let's say we choose x = -50 and y = 10. Using the same equation, we have:
(-50) + 10 + z = -84
-40 + z = -84
Solving for z, we get:
z = -44
Therefore, another solution can be x = -50, y = 10, and z = -44.
Now, let's move on to finding three numbers that add up to 54.
Using the same approach, we can set up the equation:
x + y + z = 54
Let's choose x = 0 and y = 54 as our initial values. Substituting these values into the equation, we have:
0 + 54 + z = 54
54 + z = 54
Simplifying further, we get:
z = 0
So, one solution can be x = 0, y = 54, and z = 0.
For another solution, let's choose x = 20 and y = 10. Substituting these values into the equation, we have:
20 + 10 + z = 54
30 + z = 54
Solving for z, we get:
z = 24
Thus, another solution can be x = 20, y = 10, and z = 24.
These are just two examples, and there can be infinite combinations of numbers that add up to a given sum. By choosing different initial values for x and y and solving for z, you can find more solutions.
