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

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 = 0

or 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.

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.
