¡Vamos a resolver las ecuaciones! Primero, analicemos cada una de ellas: 1. Para \( \frac{2 x}{9}=15 \), multiplicamos ambos lados por 9 para despejar \(x\): \[ 2x = 135 \quad \Rightarrow \quad x = \frac{135}{2} = 67.5 \] 2. Para \( \frac{6 x+1}{3}=5 \), multiplicamos por 3: \[ 6x + 1 = 15 \quad \Rightarrow \quad 6x = 14 \quad \Rightarrow \quad x = \frac{14}{6} \approx 2.33 \] 3. Para \( \frac{6}{x}=3 \), multiplicamos: \[ 6 = 3x \quad \Rightarrow \quad x = 2 \] 4. Para \( -\frac{12}{x}=4 \), multiplicamos por \( -x \): \[ 12 = -4x \quad \Rightarrow \quad x = -3 \] 5. En \( -\frac{2 x+2}{x} \), eliminar el denominador nos da: \[ -2x - 2 = 0 \quad \Rightarrow \quad -2x = 2 \quad \Rightarrow \quad x = -1 \] Así que las soluciones son: 1. \(x = 67.5\) 2. \(x \approx 2.33\) 3. \(x = 2\) 4. \(x = -3\) 5. \(x = -1\)
