d $\frac{35}{3}$

Work Step by Step

You have the inequality:(3d−7) $\gt$28. Separate it into two inequalities:3d−7$\lt$ −28 or 3d−7$\gt$28 and solve them individually: 3d−7$\lt$−28 (add 7 to both sides) 3d$\lt$−21 (divide both sides by 3) d$\lt$−7 3d−7$\gt$28 (add 7 to both sides) 3d$\gt$35 (divide both sides by 3) d$\gt$ $\frac{35}{3}$ d$\lt$−7 or d$\gt$ $\frac{35}{3}$
