It is 729.
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
The value of x that satisfies -9 multiplied by x equals 1 is x = -1/9.
9 X 9 = 81
x=9
-9
If x=9, x=9
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
The value of x that satisfies -9 multiplied by x equals 1 is x = -1/9.
9 x 9 x 9 = 729
9 X 9 = 81
x=9
-9
If X = 9 then 5X would = 5 x 9, which is 45.
9
There is no answer it it just stays 9-x
X = 72 72 divided by 9 equals 8
If x-3x=18 then x equals -9
