4s + 5 = 19 First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5. Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14. Third, divide both sides by 4. / Your problem should look like: s = . Fourth, simplify to . / Your problem should look like: s = which is the answer.
