if this is (y+3)/y = 9: 9 can also be written as 9/1 therefore if you cross multiple across the parenthesis, 9y = y+3; 8y = 3; y = 3/8 if this is y + 3/y = 9; the equation can be multiplied by y on both sides and set equal to 0 to get...

Because math is complicated. You have to understand the process.
