Question

How do you solve `4/5d = -12`?

Answer 1

See the entire solution process below:

Explanation:

To solve, multiply each side of the equation by `color(red)(5/4)` to solve for `d` while keeping the equation balanced:

`color(red)(5/4) xx 4/5d = color(red)(5/4) xx -12`

`color(red)(cancel(5)/cancel(4)) xx color(red)(cancel(color(black)(4)))/color(red)(cancel(color(black)(5)))d = -60/4`

`d = -15`
