Answer:

x = -1.33333333333

Explanation:


\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}


-2x+1-1=4x+9-1


\mathrm{Simplify}


-2x=4x+8


\mathrm{Subtract\:}4x\mathrm{\:from\:both\:sides}


-2x-4x=4x+8-4x


\mathrm{Simplify}


-6x=8


\mathrm{Divide\:both\:sides\:by\:}-6


(-6x)/(-6)=(8)/(-6)


x=-(4)/(3)


x=-1.33333333333
