Work Step by Step
Create a table with values of b and the corresponding values of the equation. Look for a 17 in the second column.
$\underline{\ b\ }\ \ \ \ \ \underline{6b-3}$
$\ 1\ \ \ \ \ \ \ \ \ \ \ \ \ 3$
$\ 2\ \ \ \ \ \ \ \ \ \ \ \ \ 9$
$\ 3\ \ \ \ \ \ \ \ \ \ \ 15_\longrightarrow$ The solution is between 3 and 4.
$\ 4\ \ \ \ \ \ \ \ \ \ \ 21$
