Answer:

x=5/2 + a/2,  y= 5/2 - a/2

Step-by-step explanation:

We can solve this system using addition of the equations

x+y=5

x-y=a

2x  =(5+a)

x=(5+a)/2= 5/2 +a/2

x=5/2 +a/2

x-y=a

y = x - a , x=5/2 + a/2

y= 5/2 + a/2-a

y= 5/2 - a/2

Answer:

x=\frac{a+5}{2}  y=5-\frac{a+5}{2}  

Step-by-step explanation:

x+y=5

y=5-x

x-y=a

x-(5-x)=a

2x-5=a

2x=a+5

x=\frac{a+5}{2}  

x+y=5

\frac{a+5}{2}  +y=5

y=5-\frac{a+5}{2}
