So the question is Solve by Elimination: {2x+y=10 and x+y=2. Show Your Work.
I think it is Solve by elimination by addition but I could be wrong.
The way I thought it was is {2(2)=10
I have (2) because x+y=2 so I thought I needed to just change the x+y in the 2x+y=10 equation but I know Im wrong.
Someone please help me!
