multiply the first by 6 and the second by 7, then add the new equations.
It should be rather straightforward from there.
help me understand how to solve this problem x+4y=17
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Second, what are you trying to solve? You cannot get the numerical values of x and y with only one equation.
x = 17 - 4y
y = (17 - x)/4
I hope this helps. If not, repost your question in clearer terms.
