3. SOLUTION:[tex]\begin{aligned} (f + g)(x) & = f(x) + g(x) \\ & = (3x + 2) + (4 - 5x) \\ & = 3x + (-5x) + 2 + 4\\ & = \boxed{-2x + 6} \end{aligned}[/tex]4. SOLUTION:[tex]\begin{aligned} (f - g)(x) & = f(x) - g(x) \\ & = (x + 5) - (2x - 1) \\ & = x - 2x + 5 - (-1) \\ & = x - 2x + 5 + 1 \\ & = \boxed{-x + 6} \end{aligned}[/tex]
