Adjust Fractions based on the LCM

= \frac{k + 1}{2 ( k + 1 )} - \frac{2}{2 ( k + 1 )}

Apply the fraction rule:

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

= \frac{k + 1 - 2}{2 ( k + 1 )}

Subtract the numbers:

1 - 2 = - 1

= \frac{k - 1}{2 ( k + 1 )}

∣ 7 m ∣ + 4 = 25

3 q^{2} - q - 14 = 0

\frac{2}{2} - \frac{1}{2}

\frac{x}{6} = \frac{5}{4}

9 + 7 x = 7 x^{2}
