-7d + 8 < 29
Subtract 8 from both sides:
-7d < 21
Divide both sides by -7 --- However, when you multiply or divide both sides of an inequality by a negative number, you must change the direction of the inequality. You do not change the direction if you multiply or divide by a positive, or if you are adding or subtracting:
d > -3
-7d + 8 < 29
