Question

Solve the following system of equations. Please show your work to receive full credit.
x - y = 16
2x + y = 2

Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

Hint: Add the equations together to get


x - y = 16
2x + y = 2
----------
3x + 0y = 18

So

3x = 18

Answer 2

i think it's like this:
to find the value of x you must first get rid of the y, so make whatever number is with y in both equations equal each other and adding them would get rid of them, since one would be positive and one would be negative
