Question 227782
How would I solve for x?


{{{-3x+6(x+4)=9}}}


Step 1.  Multiply to get rid of the parenthesis.


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


Step 2.  Combine x-terms


{{{3x+24=9}}}


Step 3.  Subtract 24 from both sides of the equation


{{{3x+24-24=9-24}}}


{{{3x=-15}}}


Step 4.  Divide by 3 to both sides of the equation


{{{3x/3=-15/3}}}


{{{x=-5}}}


Step 5.  Substitute {{{x=5}}} into the original equation {{{-3x+6(x+4)=9}}} to check solution.


{{{-3*(-5)+6(-5+4)=9}}}


{{{15+(-6)=9}}}


{{{9=9}}} which is a true statement.


Step 6.  ANSWER:  Solution is {{{x=-5}}}.


I hope the above steps were helpful.
