Question

The sum of two numbers is 46 and the difference is 10 . What are the numbers?

Answer 1

Answer: 28 and 18

Step-by-step explanation:

I used the guess and test strategy to find that:  

28 - 10 = 18

28 + 18 = 46

Answer 2

X + y = 46
x - y = 10
*add these 2 equations

x + y + x - y = 46 + 10
2x = 56
x = 28

x - y = 10
28 - y = 10
*subtract 28 from both sudes
- y = 10 - 28
*multiply by -1
y = 28 - 10
y = 18
