write the difference between 35 and 16
Answers
The sum of two numbers is 35 and their difference is 16. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
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 16. In other words, x minus y equals 16 and can be written as equation B:
x - y = 16
Now solve equation B for x to get the revised equation B:
x - y = 16
x = 16 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 35
16 + y + y = 35
16 + 2y = 35
2y = 19
y = 9.5
Now we know y is 9.5. Which means that we can substitute y for 9.5 in equation A and solve for x:
x + y = 35
x + 9.5 = 35
X = 25.5
Summary: The sum of two numbers is 35 and their difference is 16. What are the two numbers? Answer: 25.5 and 9.5 as proven here:
Sum: 25.5 + 9.5 = 35
Difference: 25.5 - 9.5 = 16
