    The answer is 4.

    Explanation:

    If we are trying to know how many people watched the show, we have to substract 26 that watched none of the shows, so:

    151-26=125

    Now that we know the numbers, the easiest way to know the "x" is with a Venn Diagram. But the equation is also quiet simple.

    125 (total people) - 68 (Law and Disorder) - 61 (25) - 52 (The Tenors) + 16 (Law and Disorder"" and ""25"") + 25 ("Law and Disorder"" and ""The Tenors") + 19 (""25 "" and ""The Tenors"") = 4

    That is: 15-68-61-52+16+25+19=4

    4 people watch all three shows.
