In the expression 3x + 7 the term 3 is the coefficient of the variable x
What is algebraic expression?
An algebraic expression is a mathematical phrase involving numbers, variables, and operations. It may include terms, coefficients, constants, and variables combined using addition, subtraction, multiplication, and division.
In the expression 3x + 7, the term 3x consists of two parts: the coefficient 3 and the variable (x). The coefficient represents the numerical factor by which the variable is multiplied.
So, the term 3x means "three times x"
The term 7 is a constant term because it doesn't involve a variable.
Therefore, the 3 in 3x + 7 is the coefficient of the variable x.
