mid point of xy

It equals y+1

true

xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y

xy + xy = 2xy

x and y are being combined using a binary operation called "plus" and the result is xy.

x+xy=8 xy=-x+8 y=-1+8/x

It is an expression in the form of: xy+7

Yes

It cannot be a property since it is not generally true!

xy + z

xy = x ÷x y = 1

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

x = 6y over (y-6)

That is the commutative property of equality.

That equals 2xy + 3y which factors to y(2x + 3)

It is an expression in the form of: xy+7

2+2y+x+xy=(x+2)(y+1)

xy + x + y + 1 = (x + 1)(y + 1).

its 5 because if y is 3 then u have to ask yourself wat times 3 + 7 is 22

between X and Y

a circle

xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.

xy(x + 1)(x + 2)

"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
