Answer 3

Im going to start with the second problem.
-4y=6-8x divide both sides by -4 to get y=2x-3/2
then take the first problem and plug 2x-3/2 in for y
so our first equation should be (2x-3/2)-2x-1=o

Answer 4

ok

Answer 5

once we have 2x-3/2-2x-1=0 we are going to solve for x.
2x-2x is 0 and -3/2-1 is -5/2
we end up with -5/2=0 which is impossible so there is no solution

Answer 6

do you understand how I found the answer?
