Question

Solve the following system of equations. Please show your work to receive full credit.

x - y = 10
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

x - y = 10 . . . (1)
2x + y = 2 . . . (2)

(1) + (2) => 3x = 12
x = 12/3 = 4

From (1), 4 - y = 10
y = 4 - 10 = -6

x = 4, y = -6


I used elimination method.
