Find the ordered pair (x,y)  that satisfies the system of equations

   

 

                   x + y = 15

 

                   x - y = 3

 

 

 

 

\(\begin{align*} x+y&=15,\\ x-y&=3. \end{align*}\)

Add both equations up and the y's cancel out. So we have:

2x = 18

x = 9

Plug this into our first equation:

9 + y = 15

y = 6

So (9, 6)
