29.91 - 1.35p=-5.7 (-6p - 4)

p = 0.2

Step-by-step explanation:

Step 1: Distribute

29.91 - 1.35p = - 5.7 (-6p - 4)

29.91 - 1.35p = 34.2p + 22.8

Step 2: Add 1.35p to both sides

29.91 - 1.35p + 1.35p = 34.2p + 22.8 + 1.35p

29.91 = 35.55p + 22.8

Step 3: Subtract 22.8 from both sides

29.91 - 22.8 = 35.55p + 22.8 - 22.8

7.11 = 35.55p

Step 4: Divide both sides by 35.55

7.11 / 35.55 = 35.55p / 35.55

0.2 = p

Answer: p = 0.2
