X = 2
-3
To solve for X in the equation "X over 9 equals 1 over 16," we can cross multiply. This gives us 16X = 9. Dividing both sides by 16 gives us X = 9/16.

0.5625/9 = 1/16 x/9 = 1/16 ⇒ x = 9 x 1/16 = 9/16 = 0.5625
80 x/5 = 16 x/5 x 5/1 = 16 x 5/1 x = 80
x=-16
That can be written as 2 x 2 x 2 x 2 and it equals 16.
You have to know what x and y equals first!
= Z X and Y are examples. 2 to the power of X multiplied by 2 to the power 2 equals 16 What is X? X=2 2 to the power of 2 (2x2) multiplied (X) by 2 to the power of 2 (2x2) (2x2)4 X (2x2)4 = 4X4 = 16
