Question 688286
{{{-3+12x=-9x-5}}} Start with the given equation.



{{{12x=-9x-5+3}}} Add {{{3}}} to both sides.



{{{12x+9x=-5+3}}} Add {{{9x}}} to both sides.



{{{21x=-5+3}}} Combine like terms on the left side.



{{{21x=-2}}} Combine like terms on the right side.



{{{x=(-2)/(21)}}} Divide both sides by {{{21}}} to isolate {{{x}}}.



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


Answer:


So the solution is {{{x=-2/21}}}
