Answer 1

$a) \frac{x}{9} = 3 = > x = 9 \times 3 = 27 \: \in \: \mathbb{Z}$

$b) \frac{y}{ - 11} = 11 = > y = - 11 \times 11 = - 121 \: \in \: \mathbb{Z}$

$c) \frac{z}{ - 13} = - 12 = > z = - 13 \times ( - 12) = - 156 \: \in \: \mathbb{Z}$

$d) \frac{a}{ - 17} = 11 = > a = - 17 \times 11 = - 187 \: \in \: \mathbb{Z}$

$e) \frac{m}{1} = 34 = > m = 34 \: \in \: \mathbb{Z}$

$f) \frac{n}{ - 1} = - 54 = > n = - 1 \times ( - 54) = 54 \: \in \: \mathbb{Z}$

$g) \frac{u}{ - 18} = 43 = > u = - 18 \times 43 = - 774 \: \in \: \mathbb{Z}$

$h) \frac{v}{ - 89} = - 9 = > v = - 89 \times ( - 9) = 801 \: \in \: \mathbb{Z}$
