See a solution process below:

First, expand the terms within the parenthesis by multiplying each term inside the parenthesis by the term outside the parenthesis:

#4x + 3 - color(red)(3)(x + 5) =>#

#4x + 3 - (color(red)(3) xx x) - (color(red)(3) xx 5) =>#

#4x + 3 - 3x - 15#

Now, group and combine like terms:

#4x - 3x + 3 - 15 =>#

#(4 - 3)x + (3 - 15) =>#

#1x + (-12) =>#

#x - 12#
