4x-y=-4 2x+y=7 Using Elimination, Solve.
add the two equations together. you get 6x=3. then solve for x, plug back in to get y. Tada :)
I have 2 questions by the way
You can either replace x or y using the first equation. Replace the variable in the second equation and you will get x and y.
By elimination, do you mean the trial and error method?
Idk you start it off by what that person did up there^ I think I did it right idk though.
