Answer:

See the entire simplification process below:

Explanation:

First, expand the terms in parenthesis by multiplying each term within the parenthesis by #color(red)(3)#. Be careful to handle the signs of the individual terms correctly:

#-4x + color(red)(3)(2x - 5) ->#

#-4x + (color(red)(3) xx 2x) - (color(red)(3) xx 5) ->#

#-4x + 6x - 15#

Now, combine like terms:

#(-4 + 6)x - 15 ->#

#2x - 15#
