Question 152725


{{{6(d-1)=3(d+5)}}} Start with the given equation.



{{{6d-6=3d+15}}} Distribute.



{{{6d=3d+15+6}}} Add {{{6}}} to both sides.



{{{6d-3d=15+6}}} Subtract {{{3d}}} from both sides.



{{{3d=15+6}}} Combine like terms on the left side.



{{{3d=21}}} Combine like terms on the right side.



{{{d=(21)/(3)}}} Divide both sides by {{{3}}} to isolate {{{d}}}.



{{{d=7}}} Reduce.
