Solution, x+7+2x<-3x\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&amp;\:x<-(7)/(6)\:\\ \:\mathrm{Decimal:}&amp;\:x<-1.16667\dots \\ \:\mathrm{Interval\:Notation:}&amp;\:\left(-\infty \:,\:-(7)/(6)\right)\end{bmatrix}


Steps:


x+7+2x<-3x


\mathrm{Group\:like\:terms}, x+2x+7<-3x


\mathrm{Add\:similar\:elements:}\:x+2x=3x, 3x+7<-3x


\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}, 3x+7-7<-3x-7


\mathrm{Simplify}, 3x<-3x-7


\mathrm{Add\:}3x\mathrm{\:to\:both\:sides}, 3x+3x<-3x-7+3x


\mathrm{Simplify}, 6x<-7


\mathrm{Divide\:both\:sides\:by\:}6, (6x)/(6)<(-7)/(6)


\mathrm{Simplify}, x<-(7)/(6)


\mathrm{The\:Correct\:Answer\:is\:x<-(7)/(6)}


\mathrm{Hope\:This\:Helps!!!}
