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

4a + 5b =13 + 4a +b =17  6b=30 b=5 4a+5(5)=13 4a+25=13 4a=12 a=3 (3,5)
