Which of the following is not a literal equation? A. x = y + 3 B. x^2 + y^2=z^2 C. n+n=10 D. a/b = 1

A/b = 1 would not be a literal equation

if the solution to a number divided by a number is one then the two numbers would have to be the same

Example: 5/5=1

"a" and "b" are two different numbers so it would be impossible for the solution to equal one
