if you have this:
-1%2F8%2B%289%2F2%29y=-7%2F4+
%289%2F2%29y=1%2F8-7%2F4+
%289%2F2%29y=1%2F8-%287%2A2%29%2F%284%2A2%29+
%289%2F2%29y=1%2F8-14%2F8+
%289%2F2%29y=-13%2F8+
y=-%2813%2F8%29%2F%289%2F2%29+
y=-%2813%2Fcross%288%294%29%2F%289%2Fcross%282%291%29+
y=-%2813%2F4%29%2F9+
y=-13%2F36+


but, in case you have this:
-1%2F8%2B9%2F%282y%29=-7%2F4+
9%2F%282y%29=1%2F8-7%2F4+
9%2F%282y%29=-13%2F8+
8%2A9=-13%2A%282y%29+
-26y=72+
y=72%2F-26+
y=+-36%2F13+

It is very probable that the second term on the left is %289%2F2%29y and not 9%2F%282y%29.

But you will get better help with your questions if you make sure you present them clearly, using parentheses where appropriate: -1/8+(9/2)y=-7/4.

Solving is going to be much easier if you don't have to deal with all the fractions, as the other tutor did. So the first thing I would do is multiply the whole equation by the LCD, which is 8:

-1%2F8+%2B+%289%2F2%29y+=+-7%2F4
-1%2B36y+=+-14
36y+=+-13
y+=+-13%2F36
