You should of said that instead because D = 69 makes no sense because D would have to be 69 for it to = 69 without adding anything to it.
which is perfectly fine? what kind of stuff do they teach in your algebra class lol
it's perfectly fine to enter stuff like x = 8 because it's just stating the number that variable represents
let me demonstrate
x = 8, this means that x is equivalent to 8. it's the same thing as saying 8 = 8.
