nincompoop · Answer

try solving it so I know what you are not understanding or failing to comprehend.

anonymous · Answer

I don't understand it at all I don't know what to do @nincompoop

tkhunny · Answer

Since the two equations describe EXACTLY the same relationship, there are infinitely many solutions.

anonymous · Answer

@tkhunny yes but i need to write it in a formula such as y=mx+b

tkhunny · Answer

Write what?

If there is no solution, you cannot write it in that form.  It doesn't exist.

If there is a single solution, the form is (a,b), not y = mx+b

Since there are infinitely many solutions, simply delete one of the duplicate equations and you will be done.
