Answer:

x = 2

Explanation:

1) Reorder the terms

3x + 5 = 29 - 9x
3x + 5 = -9x + 29

2) Subtract 5 from both sides


3x + 5 - 5 = -9x + 29 - 5

3x = -9x + 24


3) Add 9x to both sides

3x + 9x = -9x + 9x + 24

12x = 24


4) Divide both sides by the same factor

12x/12 = 24/12

x = 2

Explanation:


\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}

3x+5-5=29-9x-5


\mathrm{Simplify}

3x=-9x+24


\mathrm{Add\:}9x\mathrm{\:to\:both\:sides}

3x+9x=-9x+24+9x


\mathrm{Simplify}

12x=24


\mathrm{Divide\:both\:sides\:by\:}12


(12x)/(12)=(24)/(12)


\mathrm{Simplify}
