<span>(8,3 - K) * 4,7 = 5,64 </span>
<span>8.3 - к = 5.64 : 4.7 </span>
<span>8.3 - к = 1.2</span>
<span>к = 8.3 - 1.2</span>
<span>к = 7.1</span>
Ответ 7.1
(9,2 - m) * 3,2 = 16
<span><span>9.2 - m = 16 : 3.2</span></span>
<span><span>9.2 - m = 5</span></span>
<span><span>m = 9.2 - 5</span></span>
<span><span>m = 4.2</span></span>
<span><span>Ответ 4.2</span></span>
