An equation contains a term with a coefficient when there is a variable multiplied by a number (the coefficient).
Among the given equations:
- 8 + 4k = 10: The term 4k has a coefficient of 4.
- abc + 3 = 9: There are no coefficients because \(abc\) is a single term.
- 8 − g + 2 = 16: The term g does not have a coefficient explicitly stated (it would be understood to be 1 if it were written as 1g).
- 18 + 1 = 19: There are no variables, thus no coefficients.
So the equation that contains a term with a coefficient is 8 + 4k = 10.
