Question

x+2y=6 (1)
x=2-2y (2)

What is the solution of the system?

Answer 1

is the ordered pair (2,-4) ??

Answer 2

x+2y=6 (1)
x=2-2y (2)
Make 2y the subject in both

2y=6 - x(1)
2y = 2-x (2)

Subtract [2] from [1]

0 = 4 (which we both know is nonesense)
Therefore no real solutions as they are parallel lines (x values identical in both equations)

Answer 3

oooh crap, well thanks lol

Answer 4

i figured it out thank you :D

Answer 5

niente!
