# 1




{{{-6=3+3x}}} Start with the given equation.



{{{0=3+3x+6}}} Add {{{6}}} to both sides.



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



{{{-3x=9}}} Combine like terms on the right side.



{{{x=(9)/(-3)}}} Divide both sides by {{{-3}}} to isolate {{{x}}}.



{{{x=-3}}} Reduce.



------------------------

Answer:


So the solution is {{{x=-3}}}

# 2




{{{-a+5=0}}} Start with the given equation.



{{{-a=0-5}}} Subtract {{{5}}} from both sides.



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



{{{a=(-5)/(-1)}}} Divide both sides by {{{-1}}} to isolate {{{a}}}.



{{{a=5}}} Reduce.

Answer:


So the solution is {{{a=5}}}
