Question

Given: x + 2 <-5.Choose the solution set.OXIXER,<-7)OXIXERX <-3)OxIXER X<3)OXIXER X<7)

Answer 1

Given:

`-(1)/(2)x>4`

Solve for x

`\begin{gathered} -(1)/(2)x>4 \\ Crossmultiply \\ -x>4*2 \\ -x>8 \\ Divide\text{ both sides by -1} \\ (-x)/(-1)<(8)/(-1) \\ x<-8 \end{gathered}`

Hence, the solution set is

`\lbrace x|x\in\Re,x<-8\rbrace`
