Question

U = b - ak, solve for a

Answer 1

Answer:  $a = -\frac{u-b}{k}$

Answer 2

Hey there!☺

$Answer:\boxed{a=\frac{b-u}{k}}$

$Explanation:$

$u=b-ak$

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:

$\frac{-ak}{-k}=\frac{-b+u}{-k}\\a=\frac{b-u}{k}$

a=b-u/k is your answer.

Hope this helps!☺
