OpenStudy (shadowfiend):

What methods can you use to solve systems of equations?

OpenStudy (anonymous):

substitution, addition, multiplication, or division.

OpenStudy (shadowfiend):

Right right. Is there one that seems like it could be particularly easy to apply here?

OpenStudy (anonymous):

substitution?

OpenStudy (shadowfiend):

Close. What happens if you add the two? Is there anything that cancels?

OpenStudy (shadowfiend):

So, honestly, substitution could work perfectly. So let's go with that.

OpenStudy (shadowfiend):

How would you go about using substitution here?

OpenStudy (anonymous):

i got x=6 and y=-10, but idk how to show work lol.

OpenStudy (precal):

|dw:1338408036590:dw| use addition method since the y's cancel out, it is an easier method. Can you find y now?
