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.

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

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

$\displaystyle 32x = 5xA$

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

$\displaystyle A = \frac{32}{5}$

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