How do I figure out how to write two pairs of numbers that have a sum of -2 5/12.One pair must be negative and one pair must be negative and positive.Thanks, any help is appreciated.

Huh?

-2 + (-5/12)

-3 5/12 + 1

To figure out how to write two pairs of numbers that have a sum of -2 5/12, you can use a system of equations. Let's call the unknown pairs of numbers "x, y" and "a, b." Now, we can set up the following equations:

Equation 1: x + y = -2 5/12
Equation 2: a + b = -2 5/12

To satisfy the condition that one pair must be negative and the other pair must be negative and positive, we can say that x and y are both negative, and a is negative while b is positive.

Now we have two equations with two unknowns that represent the sums:

Equation 1: x + y = -2 5/12
Equation 2: a + b = -2 5/12

To find the specific values of the pairs that satisfy these equations, I'll explain how to solve the system of equations by substitution:

1. Solve Equation 2 for a or b. Let's solve it for a:
a = -2 5/12 - b

2. Substitute the expression for a in Equation 1:
x + y = -2 5/12

3. Replace a in Equation 2 with its value obtained in step 1:
(-2 5/12 - b) + b = -2 5/12

4. Simplify the equation:
-2 5/12 - b + b = -2 5/12
-2 5/12 = -2 5/12

This means that any values you choose for x, y, a, and b that satisfy the condition x + y = -2 5/12 and a + b = -2 5/12 will work. For example, you could choose:

x = -1, y = -1/12
a = -2, b = 5/12

You can verify these values by plugging them into the original equations and confirming that they give you the desired sum.
