x-14=99
x=85 (I subtracted 14 from each side of the equation).
99 x 9 = 891
One possibility: 9 + 99/99 = 10
85
-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.
This equals 198.
-99

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
