I have a equavolent linear system but the question is asking me a) how is equation 3 obtained from equations 1 and 2 equation 1 y=2x equation 2 y=6-x equation 3 2y=x+6
What am I supposed to be doing here?
Have you considered what happens if you combine them by adding or subtracting?
but how do I add two equations? thats what the answrs have but I dont really get it
Just like this: y = 2x y = 6 -x -----------
It's too simple, right? :-)
