Question

-7d + 8 > 29

Answer 1

-7d + 8 > 29

-7d >29-8

-7d >21

// whenever you divide over a inequality with a negative value, you have to reverse the inequality

d < 21/-7

d < -3

Answer 2

The objective is to get the d by itself.
-7d + 8 > 29
Subtract 8 from each side.
-7d > 21
Divide -7 from each side.
d > -3
