Answer:
g(5) + h(3) = 5
Step-by-step explanation:
Step 1: solve each of the functions
g(x) = 4x - 3; g(5)
4x - 3 replace the x with 5
4(5) - 3 simplify the parenthesis
20 - 3 subtract
g(x) = 17
h(x) = -4x; h(3)
-4x replace the x with 3
-4(3) simplify
h(x) = -12
Step 2: add the results
g(x) = 17 + h(x) = -12
17 + (-12)
g(5) + h(3) = 5
