anonymous · Answer

Please show me in elimination. :)

anonymous · Answer

For part 1 solve the first or second equation for any variable and plug it into the second equation.

anonymous · Answer

How? That is what I don't get. :(

anonymous · Answer

Would x be 6?

anonymous · Answer

You have the following equation: 
x - y = 16
2x + y = 2

Solve the second one for y

y=-2x+2

anonymous · Answer

Plug this into the first equation

anonymous · Answer

-2x+2   x - (-2x+2) = 16

anonymous · Answer

x - (-2x+2) = 16 solve this for x.

anonymous · Answer

What is it? I don't understand. :(

anonymous · Answer

x=6, y=-10

anonymous · Answer

I was just showing you how to solve it using elimination.

anonymous · Answer

Oh, okay, thx, lol. :) :)

anonymous · Answer

Wait, the method I showed you was substitution, not elimination. My bad.

anonymous · Answer

Oh, well , either way is fine. :D
