Answer 3

@JohnNewman

Answer 4

yes

Answer 5

John, do you see the lines intersecting, or meeting, at any point?

Answer 6

@JohnNewman there are actually many ways to do this ill show you

The first option is that we can eliminate one of the variables.

Answer 7

no so it d

Answer 8

Correct! :)

Answer 9

y = 2x-3
y = 2x+5


multiply the first by -1

-y = -2x+3
y = 2x +5

combine

0 = 3

this means we have no solution to this problem this is a contradiction.
