Answer:
d<0
Explanation:
3+d<3-d
3+d<3-dcancel equal terms
3+d<3-dcancel equal termsd<-d
3+d<3-dcancel equal termsd<-dMove the variable to the left
3+d<3-dcancel equal termsd<-dMove the variable to the leftd+d<0
3+d<3-dcancel equal termsd<-dMove the variable to the leftd+d<0collect like terms
3+d<3-dcancel equal termsd<-dMove the variable to the leftd+d<0collect like terms2d<0
3+d<3-dcancel equal termsd<-dMove the variable to the leftd+d<0collect like terms2d<0divide both sides
