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
What methods can you use to solve systems of equations?
substitution, addition, multiplication, or division.
Right right. Is there one that seems like it could be particularly easy to apply here?
substitution?
Close. What happens if you add the two? Is there anything that cancels?
So, honestly, substitution could work perfectly. So let's go with that.
How would you go about using substitution here?
i got x=6 and y=-10, but idk how to show work lol.
|dw:1338408036590:dw| use addition method since the y's cancel out, it is an easier method. Can you find y now?
