When y itself is negative, -y becomes positive.
Suppose y is -3.
Then -y is -(-3) which is +3. Got it? Hope so.

The expression (-6ay) represents the product of -6, the variable (a), and the variable (y). It indicates that the value is negative and depends on the values of (a) and (y). If (a) and (y) are both positive, the overall expression will be negative. Conversely, if either (a) or (y) is negative, the expression will be positive.
-1
The product of 6 and a number y can be expressed as ( 6y ). This expression represents the multiplication of 6 by the variable y, which can take on different values.
Let X = *positive number 1* Let Y = *positive number 2* X times Y

17 - y
If you are talking about math then its usually " x " but if that is already use in the expression and you want to use another symbol to represent a DIFFERENT number then you can use y or a or so on.
Let X = *positive number 1* Let Y = *positive number 2* X times Y
y-7 would be the expression
It should also be a positive number. Let x be the numerator and y be the denominator. So you have +x/+y, the reciprocal would be +y/+x.
Let the original number be y Therefore the new number is given by the expression 2y + 6
It's any real number distinct from 0. For instance, in the expression x/y, where x and y are real numbers, y needs to be a nonzero real number. This is because otherwise the expression x/y is undefined (viz. x/0).
