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.

Question 960352: To visit an Museum,The admission fee for student is $8 and the admission fee for Adult is $15. In one hour, 12 adults and students enter the museum and a Total of $131 in admission was paid.
Write a linear system to model this problem and solve this problem graphically. Check you answer by substituting into the linear system you found.
I have try to do my work , please help me correct if I'm wrong:
x= # of student
y=# of adult
Linear system is:
x+y=12
8x+15y=131
***not sure if it 12 or add #of adult and student***
x-intercept: y=0
8x+15y=131
8x+15(0)=131
8x=131
x=16.375
y-intercept: x=0
8x+15y=131
8(0) +15y=131
15y=131
y=8.73
I'm not sure what I did wrong But every time I try to graph, the two intercept number are not right when I Verify.
