Question

What is the solution of the following system?

Answer 1

Given system:

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

-4x-2y=-1 ..................(2)

2*(1) -(2)

-4x-2y +4x+2y = 2-(-1)

0=3   => there is no solution because the two lines (equations) are parallel and distinct (never meet), so no solution.
