Solution steps

\frac{π}{2} - 1

Convert element to fraction:

1 = \frac{1 \cdot 2}{2}

= \frac{π}{2} - \frac{1 \cdot 2}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{π - 1 \cdot 2}{2}

Multiply the numbers:

1 \cdot 2 = 2

= \frac{π - 2}{2}

\frac{1}{x - 9} + 1 \geq 0

v^{2} - 3 v - 10

7 - 3 x = - 26
