If 1/x + 1/3х = 5, what is the value of 3x/4

marusya05 [52]

Answer:

Step-by-step explanation:

$\frac{1}{x}+\frac{1}{3x}=5\\\\\frac{1*3}{x*3}+\frac{1}{3x}=5\\\\\frac{3}{3x}+\frac{1}{3x}=5\\\\\frac{4}{3x}=5\\\\4=5*3x\\\\4=15x\\\\\frac{4}{15}=x$

x = 4/15

$\frac{3}{4}x=\frac{3}{4}*\frac{4}{15}\\\\=\frac{1}{5}$
