Hey there!☺


Answer:\boxed{a=(b-u)/(k)}


Explanation:


u=b-ak

In our first step, we will flip the equation:


-ak+b=u

Now add -b to both sides:


-ak+b+-b=u+-b\\-ak=-b+u

In our last step, we will divide both sides by -k:


(-ak)/(-k)=(-b+u)/(-k)\\a=(b-u)/(k)

a=b-u/k is your answer.

Hope this helps!☺
