Question

How do you solve the equation -7/8k=21

Answer 1

`- (7)/(8) k` = 21

First, simplify
`(7)/(8) k` to
`(7k)/(8)` / Your problem should look like:
`-(7k)/(8)` = 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k =
`(168)/(-7)`
Fourth, simplify
`(168)/(-7)` to
`(168)/(7)` / Your problem should look like: k =
`- (168)/(7)`
Fifth, simplify
`(168)/(7)` to 24. / Your problem should look like: k = -24

Answer: k = -24
