Answer:
find the sum of -44 and 55?
Step-by-step explanation:
The sum of x and y is 55. In other words, x plus y equals 55 and can be written as equation A:
x + y = 55
The difference between x and y is 44. In other words, x minus y equals 44 and can be written as equation B:
x - y = 44
Now solve equation B for x to get the revised equation B:
x - y = 44
x = 44 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 55
44 + y + y = 55
44 + 2y = 55
2y = 11
y = 5.5
Now we know y is 5.5. Which means that we can substitute y for 5.5 in equation A and solve for x:
x + y = 55
x + 5.5 = 55
X = 49.5
Summary: The sum of two numbers is 55 and their difference is 44. What are the two numbers? Answer: 49.5 and 5.5 as proven here:
Sum: 49.5 + 5.5 = 55
Difference: 49.5 - 5.5 = 44
