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 4x2=3(x4). Show your steps
