For which value of x will the fraction 7/2x-6 be undefined?

HOW TO DO THIS ?

  • MATH -

    A fraction is undefined if its denominator is zero, so set
    2x-6 = 0
    2x=6
    x = 3

    So x = 3 makes the fraction undefined.

  • MATH -

    Any fraction is undefined when the denominator is equal to zero.

    In this problem the denominator is 2x-6.

    In order to find what value of x is needed to make the denominator zero, set it equal to x and solve.

    2x-6=o

    2x=6

    x=3

    Therefore, this fraction is undefined (or has a denominator of zero) when x is equal to 3.
