Correlation does not imply causation

Step-by-step explanation:

The fact that some students played computer games while studied and got high grades doesn't mean that the two variables are related because there is no cause-effect relationship between them.

One option is they got high grades because they are intelligent and don't need too much effort to pass the exam.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
