9/2 = x/16
We can see that 8(2) = 16, so multiply by 8 to the numerator and denominator, giving:
72/16 = x/16
Getting x = 72.
You can also use cross multiplication:
144 = 2x
Divide by 2:
72 = x.

that is the same as 2 x 72 dived by 9 2 x 72/9 = 2 x 8 = 16
9 x 16 x 4 - 2 = 574
lcd(22, 12, 16, 9) = 1584 22 = 2 x 11 12 = 2^2 x 3 16 = 2^4 9 = 3^2 lcd = 2^4 x 3^2 x 11 = 1584

If you mean: (x-3)^2 +(y-9)^2 = 16 then the center of the circle is at (3, 9)
