(21)/(2x)=(30)/(3x-1)

\frac{21}{2 x} = \frac{30}{3 x - 1}

x = 7

Solution steps

\frac{21}{2 x} = \frac{30}{3 x - 1}

Cross multiply

63 x - 21 = 60 x

Move

21

to the right side

63 x = 60 x + 21

Move

60 x

to the left side

3 x = 21

Divide both sides by

3

x = 7

Verify Solutions

Find undefined (singularity) points:

x = 0, x = \frac{1}{3}

Combine undefined points with solutions:

x = 7

\frac{12}{2 x - 3} = 4

3 (x) + 7 + \frac{24}{x} = 6 x + 7

\frac{0.9764}{1} = \frac{5}{x}

2304 x^{- 4} - 100 x^{- 2} + 1 = 0

2 - 3 x^{- 1} + x^{- 2} = 0
