Question

вычисли неизвестное
х:7=84
84:х=14
х*9=216

х+52=208
45*х=180
807-х=708

Answer 1

$x \div 7 = 84 < = > x = 84 \times 7 = 588$
$84 \div x = 14 < = > x = 84 \div 14 = 6$
$x \times 9 = 216 < = > x = 216 \div 9 = 24$
$x + 52 = 208 < = > x = 208 - 52 = 156$
$45 \times x = 180 < = > x = 180 \div 45 = 4$
$807 - x = 708 < = > x = 807 - 708 = 99$
