and the only educational value of such a question would be possibly in a mathematics education course to train teachers to recognize and eliminate bad questions. We do not want students to hate mathematics because of bad questions.
I did identify it as a bad question.
You claimed it was solvable by 9th graders.
The first three equations were good, but the last equation was messed up, so it is altogether a bad question that has no place in education other than perhaps an example of a bad question.
But this is not a good mathematics problem for any course. The first three equations look like a good standard high school algebra problem to get students more used to techniques such as elimination and substitution where we have 3 unknowns and 3 equations. But the fourth equation without the double star looks like a tricky question that could be considered fun and light, but it should not be graded. But the way that the question was illustrated with the double star is just a bad math question, and the only educational value of such a question would be possibly in a mathematics education course to train teachers to recognize and eliminate bad questions. We do not want students to hate mathematics because of bad questions.

See Dr. Van Name, if all your posts were as coherent and neutral as this, then perhaps people would be interested in Reverse Compucoin, or whatever its called. Its good to see that you still have it in you to be rational. You just have to remember to put up with us who are stupider than you, which should be easy to do because its part of being smart.
I have always been coherent. I am just using fewer bad words here and being nice here. But I will give people respect if they act respectably, and I will even talk about 9th grade math. There is nothing respectable about the chlurmcks here who hate my education. The fools here need to admit that they are insufferable @$$holes who are doing nothing but convincing me that they deserve 5 more pandemics.
