(x+5)/(2x)= 3/x

\frac{x + 5}{2 x} = \frac{3}{x}

x = 1

Solution steps

\frac{x + 5}{2 x} = \frac{3}{x}

Cross multiply

(x + 5) x = 6 x

Solve

(x + 5) x = 6 x : x = 0, x = 1

x = 0, x = 1

Find undefined (singularity) points:

x = 0

Since the equation is undefined for:

0

x = 1

y, x = \frac{8}{y}

\frac{8}{x} + \frac{7}{3 x} = x + 2

R, \frac{P V}{n R} = T

65 = \frac{4.23}{( 0.13 - x )}

\frac{0.4}{x} = 2
