    This is really simple but.....(Simplifying Expressions)

    Im not sure why I'm struggling with this but I just need confirmation on something. The problem is asking me that if 4(x/8)+x/8 is simplified to 4x/A, what is A? So do I multiply 4 times x and then 4 times 8. or is it considered 1/8? Im confused.

    4\bigg(\frac{x}{8}\bigg) + \bigg(\frac{x}{8}\bigg) = \frac{5x}{8}

    \frac{5x}{8} = \frac{4x}{A}

    32x = 5xA

    \frac{32x}{5x} = A

    A = \frac{32}{5}

    Hope this helps and please don't post the same question more than once.
