Help please?
Solve by the elimination method.
4a + 4b =8
4a + b =37
Is there a solution (type an ordered pair), infinitely many solutions, or no solutions?

Well that one I got incorrect, so I need to do a similar excercise, what i'm looking for is to be shown how to do these step by step so I can learn the process myself, can you help me? Here is the next equation.. 4a + 5b =13 4a +b =17
