4s%2Bs%2F3-7=5 Start with the given equation



%283%29%284s%2Bs%2F3-7%29=%283%29%285%29 Multiply both sides by the LCM of 3. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)


12s%2Bs-21=15 Distribute and multiply the LCM to each side


13s-21=15 Combine like terms on the left side


13s=15%2B21Add 21 to both sides


13s=36 Combine like terms on the right side


s=%2836%29%2F%2813%29 Divide both sides by 13 to isolate s
