Show that the system has no solution.

x + 2y = - 4

y = - 1/2x - 4

Step-by-step explanation:

TO show that this system has no solution, use the y value in the second equation and put it in for y in the first. Then solve.

x + 2y = - 4

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

x - x - 8 = - 4

-8 = - 4

Because this is an incorrect statement, we can tell there is no solution.
