Answer
$b = 42$
Work Step by Step
$23 = b - 19$
In the equation, we should isolate the variable $b$ by joining constants together on the L.H.S. This is achieved by adding $19$ to both sides as shown below:
$23 + 19 = b - 19$
Simplifying, we have:
$42 = b$
This shows that the equation has a possible solution at the point $b = 42$
