\bf{Hey\ there!}


\bf{For:\ 4d<5+3d}


\bf{\underline{REVERSE}\ the\ equation:4d<3d+5}


\bf{First\ the\ term\ 3d\ on\ each\ of\ your\ sides!\downarrow}


\boxed{\boxed{\bf{Thus\ the\ answer\ is:d<5}}}\checkmark


\bf{For:8-3d>11}


\bf{\underline{REVERSE}\ the\ equation:-3d+8>11}


\bold{First\ you\ have\ to\ subtract\ by\ 8\ on\ your\ sides!\downarrow}


\bf{-3d+8-8>11-8}


\bf{Cancel:8-8\ because\ 8-8\ equals\ 0}


\bf{Keep:11-8\ because\ that\ helps\ us\ solve\ for\ our\ answer}


\bf{11-8=3}


\bf{New\ problem:-3d>3}


\bf{Divide\ each\ of\ your\ sides\ by\ -3}


\bf{(-3d)/(-3)>(3)/(-3)}


\bf{Cancel\ out:(-3d)/(-3)\ because\ it\ equals\ 1}


\bf{Keep:(3)/(-3)\ because\ it\ helps\ us\ solve\ for\ your\ answer}


\bf{(3)/(-3)=-1}


\boxed{\boxed{\bf{Thus\ your\ answer\ is:d<-1}}}\checkmark


\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}

Answer:

d < 5

Explanation:


4d<5+3d\qquad\text{subtract 3d from both sides}\\\\4d-3d<5+3d-3d\\\\d<5\\--------------------------\\8-3d>11\qquad\text{subtract 8 from both sides}\\\\8-8-3d>11-8\\\\-3d>3\qquad\text{change the signs}\\\\3d<-3\qquad\text{divide both sides by 3}\\\\(3d)/(3)<-(3)/(3)\\\\d<-1\\\\-------------------------\\\text{We have}\ d<5\ \text{or}\ d<-1.\ \text{Therefore}\ d<5.
