👉 A duad is a type of mathematical function that represents the solution to a system of linear equations. It consists of two variables, x and y, and has the following form: x + y = 1 y - x = 0 This means that if we have two variables, say x and y, where one variable is constant (in this case, y), then the other variable can be any number between -1 and 1. This relationship defines a line on the coordinate
