The variables are unknown, coefficients are numbers in multiplication with those unknown variables and constants are solo standing numbers.
Thus, we have:
Variables, coefficients and constants in the given algebraic expression.
Its a mathematical expression built up from integer constants, variables and algebraic operations.
Those symbols or placeholders who may change( vary ) are called variables.
Those numbers which are in multiplication with variables in the given expression are called coefficients.
Constants are numbers who are not associated in multiplication( or division) with variables in given expression.
Thus, for given expression -8z + 12y - 7.7,
we have:
z and y as variables
-8 is coefficient of z
12 is coefficient of y
-7.7 is constant.
