Answer 1

Answer:

8–4y

Step-by-step explanation:

5x–y+8 –( 5x+3y)

= 5x–y+8– 5x–3y

= 8–4y

Answer 2

Answer:

On subtracting $5x + 3y$  from $5x -y + 8$ we get , $-4( y + 2 )$ .

Step-by-step explanation:

To subtract : $5x + 3y$  from $5x -y + 8$

• Solution : Subtraction is the arithmetic operation of taking off difference between two numbers.
• To subtract given algebraic expression, we subtract like terms together .  
• Therefore, arranging given terms in correct order, we get,  $\left(5x -y + 8)-\left(5x + 3y)$
• Removing parenthesis and changing sign of terms in the second bracket .

         $= \left(5x -y + 8)-\left(5x + 3y) \\=5x -y + 8 - 5x -3y \\=-4y + 8 \\= -4 (y + 2 )$  

Note :

Question for above solution is : on subtracting $5x + 3y$  from $5x -y + 8$ it gives ?
