    Find a common denominator. For this example, your common denominator is: 15x That might help guide you.

    Well, you know: \[\frac{ 2 }{ a } + \frac{ 1 }{ a } = \frac{ 2 + 1 }{ a } = \frac{ 3 }{ a }\]

    Also, \[\frac{ 1 }{ b } + \frac{ 3 }{ d } = \frac{ 1d + 3b }{ bd }\]

    so my final answer would be 5/15x?

    Not quite. Because in order to get a 15x, you must multiply 3 by x and 2 by 15. \[\frac{ 3 }{ 15 } + \frac{ 2 }{ x } = (\frac{ 3x }{ 15x }) + (\frac{ 2(15) }{ 15x })\]

    The next step is to combine everything into one whole fraction.
