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. 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.
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
Thank YOu !
