Question

[6.02] and [6.03]
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

Elimination would be the most efficient method here because you have one y in both equations with opposite signs. Thus add the two equations to obtain

3x = 18

x = 6

Now substitute x = 6 into either of the given equations and solve for y. Let's choose the second equation.

2(6) + y = 2

12 + y = 2

y = -10

∴ the sol'n is (6, -10)
