\(\frac{1}{2} s\) = 4s - 21
First, simplify \(\frac{1}{2} s\) to \(\frac{s}{2}\) / Your problem should look like: \(\frac{s}{2} = 4s - 21\)
Second, multiply both sides by 2. / Your problem should look like: \(s = 8s - 42\)
Third, subtract 8s from both sides. / Your problem should look like: \(s - 8s = -42\)
Fourth, simplify s - 8s to -7s. / Your problem should look like: \(-7s = -42\)
Fifth, divide both sides by -7. / Your problem should look like: \(s = \frac{-42}{-7}\)
Sixth, simplify \(\frac{42}{-7}\) to \(- \frac{42}{7}\) / Your problem should look like: \(s = \frac{42}{7}\)
Seventh, simplify \(\frac{42}{7}\) to 6. / Your problem should look like: \(s = 6\)
Answer: s = 6
