Question 663942
{{{6-1(b+1)=9}}} Start with the given equation.



{{{6-b-1=9}}} Distribute.



{{{-b+5=9}}} Combine like terms on the left side.



{{{-b=9-5}}} Subtract {{{5}}} from both sides.



{{{-b=4}}} Combine like terms on the right side.



{{{b=(4)/(-1)}}} Divide both sides by {{{-1}}} to isolate {{{b}}}.



{{{b=-4}}} Reduce.
