Question 1130928
<br>
It is very probable that the second term on the left is {{{(9/2)y}}} and not {{{9/(2y)}}}.<br>
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.<br>
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:<br>
{{{-1/8 + (9/2)y = -7/4}}}
{{{-1+36y = -14}}}
{{{36y = -13}}}
{{{y = -13/36}}}
