Question 238100: Help, how and what does this mean mean?
f(x) = 8 + x
g(x) = x - 5
If d(x) = f(x) - g(x), find d(x)

This is a substitution problem.
-------
Given:
f(X) = 8 + X
g(X) = X - 5
d(X) = f(X) - g(X), find d(X)
All you need to do now is plug (8 + X) in for f(X) and plug (X - 5) in for g(X) into the d(X) equation.
rewrite the equation
