what two numbers have the sum of 30 and the difference of 20?

Answer 1

1.The sum of 30 2.The difference of 20

x+y = 30 x-y = 20 (Then we need add both equations)

2x = 50 (y is cancelled due to opposite operations)

x = 50/2

x = 25.

25+y = 30

y = 30-25

y = 5.

25+5 = 30. 25-5 = 20.

The answer is X=25 and Y=5.

Answer 2

The answer is that x=25 and y=5. You get these answers by completing the equations x+y=30 and x-y=20.
