4 = \frac{12}{x - 1}

x = 4

Solution steps

4 = \frac{12}{x - 1}

4

x - 1 = 3

Move

1

to the right side

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = 4

\frac{1}{2 m} = 9

\frac{100}{324} = \frac{31}{x}

\frac{80}{x} = \frac{40}{100}

1 + 0.1 = (1 - d)^{- 1}

10.5 = \frac{2500}{x}
