Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
-7x – y = -30
4x + y = 21
Try this one using the steps in the problem I did for you as a guide.
Okay here is what I have
-14x - y = 60
4x + y = 14
-28x + y = -46
Now I am not sure what to do I am kinda lost being 2 goes into both with
-14 and 23 can you give me some help please.
x=2 is a solution to 4x-2=3(x-4). Show your steps
