\(- \frac{7}{8} k\) = 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
