Question 729381
you are almost correct lets do the first bracket term by term
being careful when multiplying positive and negative numbers together
{{{-(1/2)*((10q)/1)=-(10q)/2}}} = -5q 
{{{-(1/2)*(-2/1)=2/2}}} = 1
giving us -5q + 1
now we'll consider the second bracket
{{{+(1/3)*(2/1)=2/3}}}
{{{+(1/3)*(-3q)=-(3q)/3}}} = -q
putting these together gives
{{{-5q+1+(2/3)-q}}}
simplifying gives 
{{{1(2/3)-6q}}}
