The hibiscus, plumeria, and cassis petals are such a sweet-fruity flower smell that it reminds you of nectar instead of dry, dead flowers. Whereas most floral smells are dry, musky, and almost stifling this fragrance oil is sweet and almost a bit tangy.
The Standard Form for a linear equation in two variables, x and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.
A linear equation is an algebraic equation of degree 1. For example, 4x + 5 = 0 is a linear equation of one variable. x + y + 5z = 0 and 4x = 3w + 5y + 7z are linear equations of 3 and 4 variables respectively.
