This is a rational equation, so we should first clear
denominators. Multiply both sides by *x*.

We are ready to transpose. Subtract *x* from both sides.

Factor out the *x*

Divide both sides by the coefficient of the unknown.

Copy down the original equation

except that whenever you see an *x*, copy down the solution in
parentheses.

On the top of the left, we are adding fractions. For this we need common denominators.

or

which simplifies to

= *B*

If we cancel at this point, we see that it checks.
