The sum of two numbers is 53 and the difference is 15 . What are the numbers?
2 answers:
Answer:
34 and 19.
Step-by-step explanation:
Since the sum of the two numbers is 53, x+y=53. Since the difference is 15, x-y=15.
Adding x+y=53
and x-y=15,
The ys cancel, leaving 2x=68, or x=34. Therefore, 34-y=15, or y=19.
Answer:
34 and 19.
Step-by-step explanation:
If the numbers are x and y:
x + y = 53
x - y = 15 Add the 2 equations:
2x + y - y = 68
2x = 68
x = 34.
As they add up to 53:
y = 53 - 34 = 19.
