Question

The sum of three number is -44.85. One of the numbers is 24.6. The other two number are equal to each other. What is the value of each of the other two number?

Answer 1

Let the number be x. The other number is also x.

Given the first number is 24.6 and sum is -44.85
24.6 + x + x = -44.85

Combine like terms:
2x + 24.6 = -44.85

Add 24.6 on both sides:
2x = -44.85 - 24.6

Evaluate Right Hand Side:
2x = -69.45

Divide both sides by 2:
x =- 34.725

Answer: The two numbers are both  -34.725.
