    add \[\huge\rm \color{ReD}{f(x)} +\color{blue}{g(x)}\] f(x) =3 so replace f(x) by 3 and g(x) by 6x+4 last and f!nal step combine like terms

    alright okay so there is a negative sign first step is to distribute 2nd parentheses by negative one

    \[\huge\rm (−9x+7) -(x−13 )\] we need to put parentheses bec of negative sign
