The weight of one chair is $\fbox{\bf9.73\,{\text{lb}}}$ .

Further explanation:

The weight of a table and 8 chairs together is $235.68\,{\text{lb}}$ .

The weight of the table is 157.84 lb.

Therefore the weight of 8 chairs is calculated as follows:

$235.68-157.84=77.84$

The weight of 8 chairs is obtained as 77.84 lb.

Consider the cost of 1 chair as $x$ .

Then the cost of 8 chairs can be written as $8x$ .

Therefore the equation can be written as follows:

$\begin{aligned}8x&=77.84\hfill\\x&=\frac{{77.84}}{8}\hfill\\x&=9.73\hfill\\\end{aligned}$

Here, $x$ represents the weight of 1 chair.

Thus, the weight of 1 chair is obtained as $\fbox{\bf9.73\,{\text{lb}}}$ .
