Hi,
Here is my work:
Equation;
[tex] \frac{q}{2} \leqslant - 8[/tex]
Multiply both sides of inequality by 2.
[tex]2 \times \frac{q}{2} \leqslant - 2 \times 8[/tex]
Reduce the numbers with greatest common divisor 2.
[tex]q \leqslant - 2 \times 8[/tex]
Multiply the numbers.
[tex]q \leqslant - 16 \: \: \: \: \: \: \: \: \: \: \: \: result[/tex]
Hope this helps.
