Answer:

#-3x +17#

Explanation:

It is important to know and use the correct terminology in Algebra.

Variables are unknowns which can change their values - we use letters to show them.
#a, b, m, p, t , x, y, z# are all variables.

Constants are values which stay the same and always have the same value. We call them numbers:

#17, -51, 72, 1/2, -27, -2 3/4# are all constants.

The numerical coefficient is the number part of a term.
The literal coefficient is the letter(variable) part of a term

In the term #3x^2 y," " 3# is the numerical coefficient.
#color(white)(...............................) x^2y# is the literal coefficient.

So in this case, we want a variable with a coefficient of #-3# and a constant of 17. We will write two separate terms.

#-3x+17#
