In the equation 3x + 7 = 32, the number 7 is a constant term. In algebraic expressions and equations, terms can be classified as either variables or constants. Variables, often represented by letters like 'x' in this case, are symbols that can take on different values. On the other hand, constants are fixed numerical values that do not change.
In this specific equation, 3x + 7 = 32, the term "3x" is a variable term because it contains the variable 'x,' which can vary based on different values. The term "7" is a constant term because it is a fixed numerical value that does not depend on any variable; it remains constant throughout the equation.
Constants are essential in equations as they contribute to the overall balance of the mathematical expression. In solving equations, the goal is often to isolate the variable on one side of the equation, and constants play a crucial role in achieving this balance. In summary, in the equation 3x + 7 = 32, 7 is a constant term, providing a fixed value that contributes to the mathematical relationship expressed in the equation.
