Question 1176739
<br>
This is the equation you show:<br>
{{{5b/8b - 3a - a/8b - 3a = 1/5}}}<br>
I doubt that is what you intend....<br>
Use parentheses!<br>
I could guess where the parentheses are supposed to be and what the equation is supposed to be; but that's not my job.  It is YOUR job to post the equation in the correct form.<br>
Re-post, showing the correct equation.<br>
