%2816%2F30%29s%2B%2816%2F35%29s%2B%2816%2F20%29s=17 Start with the given equation



%28420%29%28%2816%2F30%29s%2B%2816%2F35%29s%2B%2816%2F20%29s%29=%28420%29%2817%29 Multiply both sides by the LCM of 420. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



224s%2B192s%2B336s=7140 Distribute and multiply the LCM to each side



752s=7140 Combine like terms on the left side


s=%287140%29%2F%28752%29 Divide both sides by 752 to isolate s



s=1785%2F188 Reduce

--------------------------------------------------------------
Answer:
So our answer is s=1785%2F188 (which is approximately s=9.49468085106383 in decimal form)
