(100-x)/(x-91)= 15/3

\frac{100 - x}{x - 91} = \frac{15}{3}

x = \frac{185}{2}

Decimal

x = 92.5

Solution steps

\frac{100 - x}{x - 91} = \frac{15}{3}

Cross multiply

300 - 3 x = 15 x - 1365

Move

300

to the right side

- 3 x = 15 x - 1665

Move

15 x

to the left side

- 18 x = - 1665

Divide both sides by

- 18

x = \frac{185}{2}

Verify Solutions

Find undefined (singularity) points:

x = 91

Combine undefined points with solutions:

x = \frac{185}{2}

6 p - \frac{2}{p} = 1

\frac{1}{x ^{a}}

\frac{x + 6}{3 - x} = \frac{5 + 2 x}{7 x - 5}

\frac{2}{y ^{2} - 9} = \frac{5}{y ^{2} + 3 y}

x + \frac{x}{x - 5} = \frac{5}{x - 5}
