2%2812%2B7%29=9b-1 Start with the given equation.


24%2B14=9b-1 Distribute.


38=9b-1 Combine like terms on the left side.


0=9b-1-38 Subtract 38 from both sides.


-9b=-1-38 Subtract 9b from both sides.


-9b=-39 Combine like terms on the right side.


b=%28-39%29%2F%28-9%29 Divide both sides by -9 to isolate b.


b=13%2F3 Reduce.
