Ответ:
\( (1.24-x)\cdot3.6=3.888 \)
\(1.24-x=3.888:3.6=1.08\)
\(x=1.24-1.08=0.16\)
Ответ: \(x=0.16\).
\(1.1:(x+0.14)=2.5\)
\(x+0.14=1.1:2.5=0.44\)
\(x=0.44-0.14=0.30\)
Ответ: \(x=0.3\).
\(25-x:1.02=4.2\)
\(x:1.02=25-4.2=20.8\)
\(x=20.8\cdot1.02=21.216\)
Ответ: \(x=21.216\).
\(144:x-7.6=82.4\)
\(144:x=82.4+7.6=90\)
\(x=144:90=1.6\)
Ответ: \(x=1.6\).
