A) get rid of the fraction by finding the common denominator, 4. multiplying by 4 on both sides, I usually have it turned into a fraction, 4/1. The 2x=3/4, is now 8x=12/4 will be set as 8x=3. Divide 8, x=3/8.
B) The common denominator is 15. Multiply on both sides, -2/5 times 15/1 is -30/5 which becomes -6. And m/3 times 15/1 is 15m/3, 5m. divide the 5 and your answer is m=-5/6

$\mathrm{Compute\:the\:ratios\:of\:all\:the\:adjacent\:terms}:\:r=\frac{a_{n+1}}{a_n}$

$\frac{36}{6}=6,\:\quad \frac{216}{36}=6,\:\quad \frac{1296}{216}=6,\:\quad \frac{7776}{1296}=6$

$\mathrm{The\:ratio\:of\:all\:the\:adjacent\:terms\:is\:the\:same\:and\:equal\:to} \ \textgreater \ r = 6$

There is a bit more to the answer but it just explains a bit more that this question does not ask for.

Hope this helps!
