Step by Step Solution

In order to solve problem, you must evaluate (n₂ - n₁ * n₃) / n₀.

• (n₂ - n₁ * n₃) / n₀

• Evaluate n₁ * n₃ = 150

  (n₂ - 150) / n₀

• Evaluate n₂ - 150 = 420

  420 / n₀

• Evaluate 420 / n₀ = 14

  14
• The answer to the problem and the result of (n₂ - n₁ * n₃) / n₀ is 14
