%2210%B0%22%22%22%3C=%22%22+C+%22%22%3C=%22%22+%2220%B0%22+   

%2210%B0%22%22%22%3C=%22%22%285%2F9%29%28F-%2232%B0%22%29%22%22%3C=%22%22%2220%B0%22+

Multiple all three sides by 9

%2290%B0%22%22%22%3C=%22%225%28F-%2232%B0%22%29%22%22%3C=%22%22%22180%B0%22

Distribute in the middle:

%2290%B0%22%22%22%3C=%22%225F-%22160%B0%22%22%22%3C=%22%22%22180%B0%22

Add 160 to all three sides

%22250%B0%22%22%22%3C=%22%225F%22%22%3C=%22%22%22340%B0%22

Divide all three sides by 5

%2250%B0%22%22%22%3C=%22%22F%22%22%3C=%22%22%2268%B0%22
