Question

U = b - ak, solve for a

Answer 1

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!☺
