1. Answer:

   x+y=10

   x-y=5

   2x=15

   x=15/2

   x+y= 10

   15/2= 10

   y= 10-15/2

   y=20-15/2

   y=5/2

2. Step-by-step explanation:

   x+y=10————-1

   x-y=5,—————2

   Equation 1 message subtracting equation 2_____

   2x=15

   x=15/2

   put this value in equation 1____

   x+y=10

   15/2+y=10

   y=10-15/2

   y=20-15/2

   y=5/2
