\frac{3}{0.8 x} - \frac{5}{1.6 x} = 1.25

x = \frac{\frac{13.19413 \dots}{0.8} - \frac{21.99023 \dots}{1.6}}{5.49755 \dots}

Decimal

x = 0.5

Solution steps

\frac{3}{0.8 x} - \frac{5}{1.6 x} = 1.25

Multiply by LCM

\frac{3.84}{0.8} - \frac{6.4}{1.6} = 1.6 x

Switch sides

1.6 x = \frac{3.84}{0.8} - \frac{6.4}{1.6}

Simplify

\frac{3.84}{0.8} - \frac{6.4}{1.6} : \frac{\frac{4.9152}{0.8} - \frac{8.192}{1.6}}{1.28}

1.6 x = \frac{\frac{4.9152}{0.8} - \frac{8.192}{1.6}}{1.28}

Divide both sides by

1.6

x = \frac{\frac{8.05306368}{0.8} - \frac{13.4217728}{1.6}}{3.3554432}

Simplify

\frac{\frac{8.05306368}{0.8} - \frac{13.4217728}{1.6}}{3.3554432} : \frac{\frac{13.19413 \dots}{0.8} - \frac{21.99023 \dots}{1.6}}{5.49755 \dots}

x = \frac{\frac{13.19413 \dots}{0.8} - \frac{21.99023 \dots}{1.6}}{5.49755 \dots}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{\frac{13.19413 \dots}{0.8} - \frac{21.99023 \dots}{1.6}}{5.49755 \dots}

(\frac{6000}{x}) - 100 - 50 x = 250

\frac{1}{x ^{2}} + \frac{5}{x} = 7

\frac{10}{x} + \frac{3}{x - 6} = 1

\frac{1}{4 x} - \frac{1}{4} = \frac{1}{2}

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