Answer:

30 and 6

Explanation:

Let the numbers be x and y. Then

x+y=36
x−y=24

Adding the two equations together gives

2x=60

∴x=30

Substituting this back into either of the equations gives y=6

sum means add.
difference means subtract.

x + y = 36
x - y = 24  Just to make it complete, I finish the problem. Add the two equations.
=======
2x = 60 Divide by 2
x = 60/2
x = 30


x + y = 36 Substitute for x
30 + y = 36 Subtract 30
y = 36 - 30
y = 6

So the solution point is (30,6)
