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.
