You cannot have xy= anything. Only x can be there at the end.
x=5y=5 Divide 5y for all 3 sides to get 5xy=y Then divide y from both sides to get 5x=1 Therefore,
x=1/5

xy = x ÷x y = 1
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
When x equals -8 and y equals 3, the expression -xy becomes -(-8)(3). Multiplying -8 and 3 gives us -24. Therefore, -xy equals -24 in this scenario.
The GCF is xy
