How do you solve the equation -7/8k=21
loris [4]
- \frac{7}{8} k = 21

First, simplify \frac{7}{8} k to \frac{7k}{8} / Your problem should look like: -\frac{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 = \frac{168}{-7}
Fourth, simplify \frac{168}{-7} to \frac{168}{7} / Your problem should look like: k = - \frac{168}{7}
Fifth, simplify \frac{168}{7} to 24. / Your problem should look like: k = -24

Answer: k = -24
