Question 15058
First remove the parentheses.  Don't forget the negative sign on the 9:
6y-(3y+9)=17
6y - 3y - 9 = 17
3y - 9 = 17


Next add + 9 to each side:
3y- 9 + 9 = 17 + 9
3y = 26


Divide both sides by 26.

{{{ (3y)/3 = 26/3}}}
{{{ y = 26/3}}}


It doesn't come out even, but then life doesn't always come out even, does it!
