b) 18, 17
c) 16, 19
d) 12, 23

Answer 1

Answer:

x=24, y= 11

Step-by-step explanation:

If the sum of two numbers is 35 and their difference is 13, what are the numbers?

Let the two numbers be x and y.

x+y = 35

x-y = 13

Add the two equations together.

x+y = 35

x-y = 13

------------------

2x = 48

Divide each side by 2

2x/2 = 48/2

x=24

Now we can find y.

x+y = 35

24+y = 35

y = 35-24

y = 11
