(28x)/(3x-1)=10

\frac{28 x}{3 x - 1} = 10

x = 5

Solution steps

\frac{28 x}{3 x - 1} = 10

Multiply both sides by

3 x - 1

28 x = 10 (3 x - 1)

Expand

10 (3 x - 1) : 30 x - 10

28 x = 30 x - 10

Move

30 x

to the left side

- 2 x = - 10

Divide both sides by

- 2

x = 5

Verify Solutions

Find undefined (singularity) points:

x = \frac{1}{3}

Combine undefined points with solutions:

x = 5

f, f^{- 1} (x) = x^{3} + 1

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

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

\frac{1}{x} + 7 x = - 8

\frac{2}{7} = \frac{10}{t + 5}
