Hi,
Re TY
you must have meant then: Parenthesis is important when submitting questions
{{{(3y-2(y-1))/6 = -1}}}  |Multiplying both sides of the EQ by 6
    3y - 2y + 2 = -6
             y = -8
and...
{{{(3*-8 +18)/6 = (-6)/6 = -1}}} 
    
{{{3y-2(y-1)/6= -1}}}  |Multiplying thru by 6 so as all denominators = 1
  18y - 2(y-1) = -6
   18y-2y + 2 = -6
        16y = -8
          y = -8/16 = -1/2

and...
{{{3*(-1/2) - (2/6)*(-3/2) = -1}}}
