Question

How do you solve for a in `ab=6+cd`?

Answer 1

See a solution process below:

Explanation:

Divide each side of the equation by `color(red)(b)` to solve for `a` while keeping the equation balanced:

`(ab)/color(red)(b) = (6 + cd)/color(red)(b)`

`(acolor(red)(cancel(color(black)(b))))/cancel(color(red)(b)) = (6 + cd)/b`

`a = (6 + cd)/b`

Or

`a = 6/b + (cd)/b`
