Question 783539
{{{1(7a+3)+1(-a-5)=-16}}} Start with the given equation.



{{{7a+3-a-5=-16}}} Distribute.



{{{6a-2=-16}}} Combine like terms on the left side.



{{{6a=-16+2}}} Add {{{2}}} to both sides.



{{{6a=-14}}} Combine like terms on the right side.



{{{a=(-14)/(6)}}} Divide both sides by {{{6}}} to isolate {{{a}}}.



{{{a=-7/3}}} Reduce.
