Question

u= ak - b solve for a

Answer 1

To solve it for "a" is to isolate "a' in one side, by doing some algebraic operations.

U =ak -b

1) Let's rewrite it

-b+ak=u

2) Add b to both sides

-b +b +ak = u +b

ak = u+b

3) Divide both sides by k

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

4) Finally, we have it for 'a':

$a\text{ =}\frac{u}{k}\text{ + }\frac{b}{k}$
