Q:

Solve the system by the elimination method. -2x + y + 6 = 0 2x + y - 8 = 0 When you eliminate x, what is the resulting equation? 2y = 2 2y = -2 y = -2

Accepted Solution

A:
I see you want to solve    -2x + y + 6 = 0 2x + y - 8 = 0    simultaneously.  Next time, please put each equation on its own line, like this:-2x + y + 6 = 0  2x + y - 8 = 0or separate the two equations with "and" or some other symbol.We can easily eliminate x by adding these 2 equations together:-2x + y + 6 = 0  2x + y - 8 = 0-------------------        2y - 2 = 0, which yields y = 1.    This is the equation called for in this problem.                             You were not asked to find x.
