Answer 1

Check the figure attached.

Explanation:

We have

Expression in Rectangle 1= 4x+3y

Expression in Rectangle 2 = 2x-y

Their sum will be in circle 1

adding:

`4x+3y+2x-y \\=4x+2x+3y-y\\=6x+2y`

Now using the expression in Rectangle 3 and circle 3, we can find expression Of rectangle 4. Let it be Exp

`x+4y+Exp=4x+5y\\Exp=4x+5y-(x+4y)\\Exp=4x+5y-x-4y\\Exp=4x-x+5y-4y\\Exp=3x+y\\`

Now using Expression in rectangle 2 and 4 to find result for circle 3

`2x-y+3x+y\\=2x+3x-y+y\\=5x`

Now adding terms in the figure
