Demonstrate the substitutions and the results.

Answer 5

I worked it out but I'd just like a second opinion :)

Answer 6

SHOW US! We can't know what you did if you don't show us. Give us the 1st Opinion and we can provide the second.

Answer 7

-x-3y=-12
-4x+3y=-3
-----------
-5x=-15
x=3

and then

1 3+3y=12
3y=9
y=3

Answer 8

I'm going with C
Thanks anyways.

Answer 9

good work
