Least Common Multiplier of

4, 5 : 20

Adjust Fractions based on the LCM

= \frac{5}{20} - \frac{12}{20}

Apply the fraction rule:

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

= \frac{5 - 12}{20}

Subtract the numbers:

5 - 12 = - 7

= \frac{- 7}{20}

Apply the fraction rule:

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

= - \frac{7}{20}

∣ 5 - 3 x ∣ = \frac{1}{2}

\frac{- 5 x + 92}{6} = 3 x

\frac{( - 1 ) ^{3 - 1}}{5 ^{3}}

(x^{3} - 1)^{2} > 1

- 3 x^{2} = 9 x
