Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
xy = x ÷x y = 1
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 + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
That is the commutative property of equality.
mid point of xy
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
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
