Answer 2

Answer:

29 and 13 as proven here:

Sum: 29 + 13 = 42

Difference: 29 - 13 = 16

Step-by-step explanation:

The sum of x and y is 42. In other words, x plus y equals 42 and can be written as equation A:

x + y = 42

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 = 42

16 + y + y = 42

16 + 2y = 42

2y = 26

y = 13

Now we know y is 13. Which means that we can substitute y for 13 in equation A and solve for x:

x + y = 42

x + 13 = 42

X = 29
