Answer:
y is a variable
Explanation:
Algebraic Equations has Terms, Coefficients, Constants
Terms:
Terms can be expressed as a algebraic expression separated by addition or subtraction (+, - ) symbols.ie, positive and negative terms
Example:
An algebraic expression is
here 4x and 3y are terms
Constant:
A constant term is a number with no variable factors. It is a term whose value never varies remains stable.
Example:
An algebraic expression is
here 6 is the constant and it may not vary
Variables, constants, coefficients:
Variable:
A variable is a symbol or usually letter/letters used to represent:
a) an unknown quantity or number
b) any one of many numbers to indicate a general principle.
Example:
An algebraic expression is
here x anb y are variables. it may vary as variable varies
Constant:
A constant is a single number.
Coefficient:
A coefficient is a number which is in before of a variable.
Example:
An algebraic expression is
here coefficient of x is 1 and coefficient of y is 6
Comparing 3y with definitions of Variables, constants, coefficients we get 3y is not a constant or coefficient.
So that y is a variable.
Therefore given y is a variable.
