4T - 8D = 12H
The given equation can be rewritten as
T = aD + bH , where a and b are constants. What is the value of a?

A constant is a fixed value that does not change. Symbols such as a, b, c, etc., often represent constants. These constant symbols are used in algebraic expressions and equations to represent fixed values that do not change as per the above question; a and b are constants.
