Question 209771


{{{9-4(3x+1)=3(6-3x)-9}}} Start with the given equation.



{{{9-12x-4=18-9x-9}}} Distribute.



{{{-12x+5=18-9x-9}}} Combine like terms on the left side.



{{{-12x+5=-9x+9}}} Combine like terms on the right side.



{{{-12x=-9x+9-5}}} Subtract {{{5}}} from both sides.



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



{{{-3x=9-5}}} Combine like terms on the left side.



{{{-3x=4}}} Combine like terms on the right side.



{{{x=(4)/(-3)}}} Divide both sides by {{{-3}}} to isolate {{{x}}}.



{{{x=-4/3}}} Reduce.

Answer:


So the solution is {{{x=-4/3}}} which approximates to {{{x=-1.333}}}.
