Solution steps

\frac{π}{4} - \frac{3 π}{4}

Apply rule

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

= \frac{π - 3 π}{4}

Add similar elements:

π - 3 π = - 2 π

= \frac{- 2 π}{4}

\frac{( x + 1 )}{5} = \frac{( x + 3 )}{3}

4 b + 6 = 2 - b + 4

x^{2} - 6 x + 9 \leq 0

2 y \leq - 3

∣ x - 4 ∣ = - 9
