I need your help, brothers and sisters.

Find the value of X so that the median of {4, 3, 19, 16, 4, 7, 12, X} is 7.5 What do I do to solve this. Haaaaaaaaaaaaaaaaaaaaalp Sorry I entered it wrong at first. And also I don't just need an answer, can somebody explain to me the steps for this? I won't benefit in the long run just from knowing the answer without knowing how to find it.

    nine edit: eight, now. edit again: Order the numbers, and make it so 7.5 is the middle number. Since you have an even number of elements, you'll have to have two elements in the center that average to 7.5. You already have a 7, so 8 is the X.
