Solved: Use universal instantiation or universal modus
Chapter 3, Problem 3E(choose chapter or problem)
Use universal instantiation or universal modus ponens to fill in valid conclusions for the arguments in 2–4.
For all real numbers a, b, c, and d, if \(b \neq 0\) and \(d \neq 0\), then a/b + c/d = (ad + bc)/bd. a = 2, b = 3, c = 4, and d = 5 are particular real numbers such that \(b \neq 0\) and \(d \neq 0\).
