\(\displaystyle \displaystyle{x + \frac{8}{3} * x}\)
Factor out x
\(\displaystyle \displaystyle{= \ x * \left [ 1 + \frac{8}{3}\right ]}\)
\(\displaystyle \displaystyle{= \ x * \left [ \frac{11}{3}\right ]}\)
and you are done....
Now, these are perfectly ordinary fractions, nothing special about them whatsoever, so we add straight across, same as always. That leaves us with 11/3. Now, remember that we don't just have 11/3, we have 11/3 of something. But what's that something? Well, we don't know, but we're using the letter x as a placeholder. Return to the original equation and we now have:
(11/3)x = 77
Now, what do you think your next step would be?
