How do I solve the following limit?

[BrainFood]

Could someone run me through how to solve this please? I am stuck.

\displaystyle\lim_{x\rightarrow \infty} {\frac{3x+5}{x-4}}​

I worked it out. Never mind.

For others who might be interested, the simples thing to do is divide both numerator and denominator by "x":
\lim_{x\to\infty} \frac{3x+ 5}{x- 4}= \frac{3+ \frac{5}{x}}{1- \frac{4}{x}}

Now, as x goes to infinity, the terms with x in the denominator go to 0.
