Question 615856
I'll do the first one to get you started.


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



{{{-3x-6x+24=9}}} Distribute.



{{{-9x+24=9}}} Combine like terms on the left side.



{{{-9x=9-24}}} Subtract {{{24}}} from both sides.



{{{-9x=-15}}} Combine like terms on the right side.



{{{x=(-15)/(-9)}}} Divide both sides by {{{-9}}} to isolate {{{x}}}.



{{{x=5/3}}} Reduce.

Answer:


So the solution is {{{x=5/3}}}
