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
<u>x-y=a</u>
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

<u><em>Answer:</em></u>Each brother gets </span>

<span> of a sandwich
<u><em>Explanation:</em></u>We know that the total number of sandwiches is 2 and that the number of brothers is 3.
Since we are given that the sandwiches will be divided equally among the three brothers, this means that each will get an equal share.
Therefore, to get the share of each, we will simply <u>divide the number of sandwiches by the number of brother</u>s as follows:
each one will get = </span>

=

<span> of a sandwich
