#3x+y+5#

Alright, here we are just going to simply add/subtract like terms.

#=color(blue)(4x)color(red)(+2y)+8-3color(red)(-y)color(blue)(-x)#

So we have two #x# variables, two #y# variables, and 2 numerical values. We just need to add all these together separately.

Add the #x# values: #color(blue)(4x-x =3x)#

#=color(blue)(3x)+2y+8-3-y#

Add the #y# values: #color(red)(2y-y=y)#

#=3x color(red)(+y)+8-3#

And finally add the numerical values: #color(green)(+8-3 = 5)#

#=3x+y color(green)(+5)#

Hope that helps!
