Adjust Fractions based on the LCM

= \frac{3}{10} - \frac{4}{10}

Apply the fraction rule:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{3 - 4}{10}

Subtract the numbers:

3 - 4 = - 1

= \frac{- 1}{10}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{1}{10}

\frac{2 x - 1}{3} - \frac{x + 1}{4} < 1

3 x = 10

0 = 12 + 29.4 x - 4.9 x^{2}

x - 2 \geq (x - 2) (2 x^{2} - x - 15)

(\frac{15}{14})^{2} + (\frac{15}{14})^{2} = c^{2}
