解:
$\begin{aligned}1.6x - 2.4 &= 7.2 \\1.6x &= 7.2 + 2.4 \\1.6x &= 9.6 \\x &= 6\end{aligned}$
解:
$\begin{aligned}24×(2.9 + x) &= 96 \\2.9 + x &= 96 ÷ 24 \\2.9 + x &= 4 \\x &= 4 - 2.9 \\x &= 1.1\end{aligned}$
解:
$\begin{aligned}x - 0.6x &= 16.4 \\0.4x &= 16.4 \\x &= 16.4 ÷ 0.4 \\x &= 41\end{aligned}$
