The following method of converting units is called "dimensional analysis."
Write every conversion factor as a fraction. Each conversion factor fraction equals 1, so it changes units but not the value. In the end, all the undesired units cancel out leaving the desired units. Multiply the given amount by the necessary conversion factors until you arrive at the desired units.

Hi there!
Let's solve this equation step by step!
First work out the parenthesis, which can for instance be done using rainbow technique.
Subtract 2u from both sides.
Subtract 38 from both sides.
And finally divide both sides by -6, in order to isolate the variable u. Remember that dividing a negative by a negative gives a positive outcome.
Hence, the answer is u = 9.
