Question

The sum of two numbers is 6

The difference of the two numbers is 3
What are the two numbers.

Answer 1

4.5 and 1.5

Explanation:

Let the 2 numbers be x and y with x > y , then

x + y = 6 → (1)

x - y = 3 → (2)

Add the 2 equations term by term to eliminate y, that is

2x + 0 = 9

2x = 9 ( divide both sides by 2 )

x = 4.5

Substitute x = 4.5 into (1) for value of y

4.5 + y = 6 ( subtract 4.5 from both sides )

y = 1.5

The 2 numbers are 4.5 and 1.5

Answer 2

4.5 and 1.5

Explanation:

4.5+1.5=6

4.5-1.5=3(difference)
