We are given the following expression:

We are asked to solve for "u". To do that we will first subtract 7u/5 on both sides:

Solving the operations:

Now we add 1/2 on both sides:

Solving the operations:

Now we multiply both sides by 5

Simplifying the fraction to the right:

Now we divide by -12

Solving the operations we get:

Therefore the result of solving for "u" is: u = 1/24
