Answer

A solução da equação \( 15 - 3z = 9 \) é \( z = 2 \).

Solution

Passo 1: Escrevemos a equação original: \[ 15 - 3z = 9 \] Passo 2: Subtraímos 15 de ambos os lados para isolar o termo com \( z \): \[ 15 - 3z - 15 = 9 - 15 \quad \Rightarrow \quad -3z = -6 \] Passo 3: Dividimos ambos os lados por \(-3\) para encontrar o valor de \( z \): \[ z = \frac{-6}{-3} = 2 \] Portanto, a solução é: \[ z = 2 \] Observação: Nenhuma das opções fornecidas (\( z = -8 \), \( z = 8 \), \( z = -2 \), 0) corresponde à solução correta.

Extra Insights

To solve the equation \( 15 - 3z = 9 \), we first isolate the term containing \( z \). 1. Subtract 15 from both sides: \( -3z = 9 - 15 \) \( -3z = -6 \) 2. Next, divide both sides by -3: \( z = \frac{-6}{-3} = 2 \) Since \( z \) equals 2, none of the given options \( z = -8, z = 8, z = -2, \) or \( 0 \) are correct! Let's say hello to the right answer, \( z = 2 \)! 🎉
