Question

How do you solve for a in `f=np+a`?

Answer 1

See the entire solution process below:

Explanation:

Subtract `color(red)(np)` from each side of the equation to solve for `a` while keeping the equation balanced:

`f - color(red)(np) = np + a - color(red)(np)`

`f - np = np - color(red)(np) + a`

`f - np = 0 + a`

`f - np = a`

`a = f - np`
