Question

State whether true or false​
$16$ is a constant and $y$ is a variable, but $16y$ is variable.

Answer 1

A term is called a constant term if it does not contain any literal (variable).
Thus, $16$ is a constant.
A term is called a variable term if it does contain any literal.
Thus, $y$ is a variable.
Also, a combination of a constant term and the variable term is a variable term if the constant term is non-zero.
Thus, $16y$ is a variable.
Hence, the given statement is true.
