5x + 2y = 7

Answer 1

What is your question? More information is needed, if you want to find the values of x and y. Is there another xy equation?

I hope this helps. Thanks for asking.

Answer 2

That equation can be rewritten in other ways that are equivalent. One of them would be
y = (-5/2)x + 7/2

Is that what you were supposed to do?
