x₂ + x₁ = m         y₂ + y₁ = m
   2                         2

-10 = x₂
9 = y₂

2=m
5=m

Plug in given numbers

-10 + x = 2                9 + y = 5
      2                              2
Solve

-10 + x = 2*2
     2 *2

-10 + x = 4
+10        +10
         x = 14
(9 + y)/2(2) = 5 (2)
9 + y = 10
-9         -9
      y=1

Final Answer: (14,1)
