Well, honey, the coefficient of 7y is simply 7. It's like asking how many slices of cheesecake Betty White wants - she only wants one, just like there's only one coefficient in front of that y. So, in this case, the coefficient of 7y is just good ol' 7.

The coefficient of 7y is 7. In algebra, the coefficient is the numerical factor of a term with a variable. In this case, the term is 7y, where 7 is the coefficient and y is the variable. The coefficient represents the value by which the variable is multiplied.
The coefficient of 7y is 7 because 7 is the number found before the variable, y. This suggests that the given number is 7*y.
In any number ax, where a is a real number and x is a variable, a would be the coefficient and the product of that number would be a*x.
Oh, dude, like, a numeral coefficient is a number that multiplies a variable, you know, like 5x or 7y. On the other hand, a literal coefficient is a coefficient that contains a letter or a variable, like 3a or 4b. So, one's just a number, and the other's a number with a side of alphabet soup.
16+7y-8 = 7y+16-8 = 7y+8
