Beyond the Answer

Para resolver la ecuación \( 10.5r + 5 = 3r + 7 \), primero restamos \( 3r \) de ambos lados: \( 10.5r - 3r + 5 = 7 \). Simplificando, tenemos \( 7.5r + 5 = 7 \). Ahora restamos 5 a ambos lados: \( 7.5r = 2 \). Finalmente, dividimos entre 7.5: \( r = \frac{2}{7.5} = \frac{4}{15} \). Pasando a la siguiente ecuación \( -11.2x - 5x = 3 + 1 \), primero sumamos \( 3 + 1 \) para simplificarlo a \( 4 \) y luego sumamos los coeficientes de \( x \): \( -16.2x = 4 \). Dividiendo ambos lados entre -16.2, obtenemos \( x = -\frac{4}{16.2} \), que se simplifica a \( x = -\frac{20}{81} \). Para \( 12.2x - 3 = 3 \), sumamos 3 a ambos lados: \( 12.2x = 6 \). Dividiendo entre 12.2, se deduce que \( x = \frac{6}{12.2} = \frac{30}{61} \). Ahora, para \( 13x + 45 = 108 \), restamos 45: \( 13x = 63 \). Dividiendo entre 13, encontramos que \( x = \frac{63}{13} \). Finalmente, en \( P + 36 = 40 \), restamos 36 para obtener \( P = 4 \). ¡Y así, hemos encontrado las soluciones paso a paso!
