Question

How do you solve `4/5a = -20`?

Answer 1

`a = -25`

Explanation:

To solve for the variable `a`, we have to isolate it (make it by itself). To do so, multiply both sides by `5/4` so that the `4/5` multiplied to the `a` will cancel out:
`4/5a color(blue)(*5/4) = -20 color(blue)(*5/4)`

Therefore,
`a = -25`

Hope this helps!
