if you have this:
11%2F4=+7%2F%286y%29+-9%2F4.......add 9%2F4 to both sides
11%2F4%2B9%2F4=+7%2F6y+-9%2F4%2B9%2F4
20%2F4=+7%2F6y+
5%2F1=+7%2F6y+..............cross multiply
5%2A6y=+7+
30y=+7+
y=7%2F30


in case you have this:
11%2F4=+%287%2F6%29y+-9%2F4.......add 9%2F4 to both sides

11%2F4%2B9%2F4=+%287%2F6%29y
20%2F4=+%287%2F6%29y
5=+%287%2F6%29y
y=5%2F%287%2F6%29
y=30%2F7
