If Y = 0 then there is no value of X such that XY = 1.
The answer depends on whether xy are commutative numbers or operators in a permutation group.
Yes, multiplying a Positive value by a Negative value always yields a Negative product.
Assuming the two equations are: 3xy - 3 = 0 ............................................. 1 2xy = 0 ............................................. 2 Then from eq 1 xy = 1 from eq 2 xy = 0 That is not possible. Or, assuming the equation is 3xy - 3 + 2xy = 0 Then 5xy = 3 or y = 3/5x Substitute for any value of x to get the value of y

In order to answer that question, we'd need to see the drawing.
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
*Hint*=xy=x mutiplied by y.
If Y = 0 then there is no value of X such that XY = 1.
Like $2 dollars.
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
xy - xy = 0
xy + xy = 2xy
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
