\(-10x-6y=18\)

\(-8x+2y=-8\)

 

Change one thing, and the solution to the changed-equation will be (3, 8)

 

What is the change?

 

Have fun guys

Change    -10x - 6y = 18  to   -10x + 6y =18 !!. How about that?

Plug (3, 8) in.

 

\(-10(3)?6(8)=18\)

\(-30?48=18\)

 

\(?=+\)

 

Of course, that's just directly checking guest's answer.

 

But we plug (3, 8) in to solve, it might take some guessing and checking/

Did you know that you gave away the answer by giving the "values of x, y", instead of something like :"the values of x and y are 2 real positive integers"? !!

It would be insanely hard to get the answer, didn't want to make it too hard...
