Well first, you want to subtract 4/11 from both sides of the equation. To do this, you must find the common denominator between 4/11 and 9/22. The common denominator is 22. This is how it should look:
4/11 + s = 9/22 8/22 + s = 9/22 -8/22 -8/22 s = 1/22
First you have to subtract 4/11 from the variable side of the equation and the right side as well. Then you'll have s=9/22-8/22, so your answer is 1/22
