use the distributive property on both sides of the equation

-2d - 10 < -d - 7

Add 2d to both sides

-10 < d - 7

Add 7 to both sides

-3 < d

or d > -3

<-------------------------

**|--------------------------->****-3**

Everything to the right of -3 should be shaded. On your number line you can draw a circle at the point -3 and fill it in completely since this inequality includes "equals to"
