Answer:

Step-by-step explanation:
We can solve this system of equations using the elimination method.
Let's start by multiplying the first equation by 3:

Now, multiply the second equation by 5:

Since both equations have 15x, we can eliminate the x by subtracting the two equations.

Now, substitute 2 for y to solve for x:

Therefore the solution to this system of equations is:

You have to use the keywords that register to the problem
So (positive integer)-x-y can be negative
so to get a negative number as your result/answer, x+y must be greater than (positve integer) so for example
lets say (positive integer)=8
x+y must be greater than 8 to make the equation negative so
example
x=5
y=4
x+y=9
8-9=-1
did you mean to put. y= -1/2x+2 for choice b? because that's what I got as a solution
