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
