198 divided by 2 equals 99. 99 times 2 equals 198.
99 x 9 = 891
One possibility: 9 + 99/99 = 10

-x(x - 99)(X + 27) x = 0, -27, 99
x + 7y = 33 multiply through by 3: 3x + 21y = 99 Subtract the second equation from the above equation: 23y = 92 So y = 4 Substituting this value of y in the first equation, x + 28 = 33 ie x = 5 The solution is (x,y) = (5,4)
There is no way to know unless you had an equation that gives the relationship between x and y. For example, if y=2x, then when x equals 99 or x equals 100, then the value of y has a difference of 2.
The answer to this equation is the number 99. This is taught in high school math.
3 times 33 equals 99.

You are looking for a number, known as x. If you add 3 to it, it equals 99. x plus 3 equals 99. x + 3 = 99 Now you need to subtract 3 from x, so x is by itself. To keep the equation balanced- and therefore correct- you need to subtract 3 from both sides. x + 3 - 3 = 99 - 3 x = 96 And there you have it.
Technetium-99 has not a chemical equation but an isotopic symbol. This is Tc with:- to the left, as a superscript, 99- to the left as a subscript, 43
This equals 198.
