Question

Ex 5
Vaaa rog repedeeeeee
Dauuuu coroanaaaa!!!!

Answer 1

$a)7 \times x = 35$

$x = 35 \div 7$

$x = 5\:\in\:\mathbb{Z}$

$b) - 84 \times y = - 756$

$y = - 756 \div ( - 84)$

$y = 9\:\in\:\mathbb{Z}$

$c)a \times ( - 4) = 112$

$a = 112 \div ( - 4)$

$a = - 28\:\in\:\mathbb{Z}$

$d)u \times ( - 43) = - 774$

$u = - 774 \div ( - 43)$

$u = 18\:\in\:\mathbb{Z}$
