Question 157818


{{{d+4(d+6)=-1}}} Start with the given equation.



{{{d+4d+24=-1}}} Distribute.



{{{5d+24=-1}}} Combine like terms on the left side.



{{{5d=-1-24}}} Subtract {{{24}}} from both sides.



{{{5d=-25}}} Combine like terms on the right side.



{{{d=(-25)/(5)}}} Divide both sides by {{{5}}} to isolate {{{d}}}.



{{{d=-5}}} Reduce.
