Answer:

#9.5x + 5.5y#

Explanation:

First, use the distributive property to simplify #3.2(x+y)# and #2.3(x+y)#:
#3.2x + 3.2y + 2.3x + 2.3y + 4x#

Now color-code the like terms:
#color(red)(3.2x) quadcolor(blue)(+quad3.2y) quadcolor(red)(+quad2.3x) quadcolor(blue)(+quad2.3y) quadcolor(red)(+quad4x)#

Combine like terms:
#9.5x + 5.5y#

Hope this helps!
