Solution

Claro, resolveré el sistema de ecuaciones paso a paso.

Dado el sistema de ecuaciones:

  1. 4xy=7 4x - y = 7
  2. y=3x+1 y = 3x + 1

Paso 1: Sustituir la segunda ecuación en la primera. Dado que y=3x+1 y = 3x + 1 , sustituimos y y en la primera ecuación: 4x(3x+1)=7 4x - (3x + 1) = 7

Paso 2: Simplificar la ecuación resultante. 4x3x1=7 4x - 3x - 1 = 7 x1=7 x - 1 = 7

Paso 3: Resolver para x x . x=7+1 x = 7 + 1 x=8 x = 8

Paso 4: Sustituir el valor de x x en la segunda ecuación para encontrar y y . y=3x+1 y = 3x + 1 y=3(8)+1 y = 3(8) + 1 y=24+1 y = 24 + 1 y=25 y = 25

Por lo tanto, la solución del sistema de ecuaciones es: x=8 x = 8 y=25 y = 25
