 Math Central Quandaries & Queries
 Question from priya, a student: I have problem in solving these equations please help me today itself very urgent: I)2x+y=y II)pie*x+y=9

Hi Priya,

I assume these are two equations that you are to solve together to obtain values of $x$ and $y.$ What I would call a linear system or sometimes simultaneous equations.

I can help get you started. What I would do first is to add $-y$ to both sides of the first equation and then solve the resulting equation for $x.$
