30=(19^2)/(4x-20)

30 = \frac{1 9 ^{2}}{4 x - 20}

x = \frac{961}{120}

Decimal Notation

x = 8.00833 \dots

Solution steps

30 = \frac{1 9 ^{2}}{4 x - 20}

Simplify

\frac{1 9 ^{2}}{4 x - 20} : \frac{361}{4 x - 20}

30 = \frac{361}{4 x - 20}

Multiply both sides by

4 x - 20

30 (4 x - 20) = 361

Divide both sides by

30

4 x - 20 = \frac{361}{30}

Move

20

to the right side

4 x = \frac{961}{30}

Divide both sides by

4

x = \frac{961}{120}

Verify Solutions

Find undefined (singularity) points:

x = 5

Combine undefined points with solutions:

x = \frac{961}{120}

\frac{3}{b} = 9

\frac{( x - 5 )}{( x ^{2} - 4 )} = 0

\frac{- 5 x}{x ^{2} - 4} = - 3

\frac{2 x + 2}{x - 2} = 1

\frac{6}{2 x - 6} = 3
