Question: what is the difference between a coefficient and a constant in an algebraic expression?
Answer: First of all consider 5x + y - 7. The coefficients are the numbers that multiply the variables or letters. ... In 5x + y - 7 the terms are 5x, y and -7 which all have different variables (or no variables) so there are no like terms. Constants are terms without variables so -7 is a constant.
