Adding polynomials
6x - 5 is the total number of coins Nancy and Bill have.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given, Nancy has x coins
No. of coins Bill has = five coins less than 5 times of coins Nancy has
= 5x - 5
Total no. of coins Nancy and bill have = x + 5x -5
= 6x - 5
Hence, Nancy and Bill have total 6x - 5 coins.
