Question 173221


{{{2(6d+3)=18-3(16-3d)}}} Start with the given equation.



{{{12d+6=18-48+9d}}} Distribute.



{{{12d+6=9d-30}}} Combine like terms on the right side.



{{{12d=9d-30-6}}} Subtract {{{6}}} from both sides.



{{{12d-9d=-30-6}}} Subtract {{{9d}}} from both sides.



{{{3d=-30-6}}} Combine like terms on the left side.



{{{3d=-36}}} Combine like terms on the right side.



{{{d=(-36)/(3)}}} Divide both sides by {{{3}}} to isolate {{{d}}}.



{{{d=-12}}} Reduce.

Answer:


So the answer is {{{d=-12}}}
