Vamos a resolver cada una de las ecuaciones dadas:<br /><br />1. \( x - 15 = 27 \)<br /> \[<br /> x = 27 + 15 = 42<br /> \]<br /><br />2. \( 6x - 10 = -16 \)<br /> \[<br /> 6x = -16 + 10 = -6 \implies x = \frac{-6}{6} = -1<br /> \]<br /><br />3. \( 12x + 12 = 72 \)<br /> \[<br /> 12x = 72 - 12 = 60 \implies x = \frac{60}{12} = 5<br /> \]<br /><br />4. \( 5x - 15 = 15 \)<br /> \[<br /> 5x = 15 + 15 = 30 \implies x = \frac{30}{5} = 6<br /> \]<br /><br />5. \( 2x - 13 = -17 \)<br /> \[<br /> 2x = -17 + 13 = -4 \implies x = \frac{-4}{2} = -2<br /> \]<br /><br />6. \( 7x + 15 = 40 \)<br /> \[<br /> 7x = 40 - 15 = 25 \implies x = \frac{25}{7} \approx 3.57<br /> \]<br /><br />7. \( 4x + 10 = -29 \)<br /> \[<br /> 4x = -29 - 10 = -39 \implies x = \frac{-39}{4} = -9.75<br /> \]<br /><br />8. \( -10x + 5 = 35 \)<br /> \[<br /> -10x = 35 - 5 = 30 \implies x = \frac{30}{-10} = -3<br /> \]<br /><br />Por lo tanto, las soluciones son:<br />1. \( x = 42 \)<br />2. \( x = -1 \)<br />3. \( x = 5 \)<br />4. \( x = 6 \)<br />5. \( x = -2 \)<br />6. \( x \approx 3.57 \)<br />7. \( x = -9.75 \)<br />8. \( x = -3 \)
