Question 960036: I'm sure what if this is the right answer that the question is looking for. since my eng. not that good i have hard time understanding But did I try best to answer what i think . Please help me.

Question:
write a situation that can be modeled by the following linear system. Explain what each variable means, then write a related problem.
(*** not understand this part***) Attempt to solve this problem by guessing at the values of x and y . For example, 100 and 30 add to 130, but do they satisfy the other equation? Try similar sets of numbers to find the set that satisfies both.
x+y=130
x-y=10

my answer:
From the first equation, the sum of two numbers is 130
From the second equation, the different of two numbers is 10
let x represent the greater number and let y represent the lesser number
then a problem could be:
The sum of two numbers is 130
The different of the two numbers is 10.

Comment:: Since the difference is only 10 the 2 numbers are
close to each other----
1st guess:: 60 and 70
Checking:: 60+70 = 130 ; 70-60 = 10*
lesser = y = 60
other = x = 70
