Change the inequality to an equation and solve the equation. Use the solution(s) to the equation to divide the number line into regions. Test a point in each region to determine if the region is part of the solution or not.

$≈ 0.54 < b < ≈ 7.46$

Refer to part (a).

Divide both sides by $2$ before trying to solve the inequality.

$x > 5$
