Answer: 25 and 10 are the answers
Step-by-step explanation: The sum of x and y is 35. In other words, x plus y equals 35 and can be written as equation A:
x + y = 35
The difference between x and y is 15. In other words, x minus y equals 15 and can be written as equation B:
x - y = 15
Now solve equation B for x to get the revised equation B:
x - y = 15
x = 15 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 35
15 + y + y = 35
15 + 2y = 35
2y = 20
y = 10
Now we know y is 10. Which means that we can substitute y for 10 in equation A and solve for x:
x + y = 35
x + 10 = 35
X = 25
Summary: The sum of two numbers is 35 and their difference is 15. What are the two numbers? Answer: 25 and 10 as proven here:
Sum: 25 + 10 = 35
Difference: 25 - 10 = 15
