Respuesta:
[tex]3x + 2y = 8 \\ 3x = 8 - 2y \\ x = \frac{8 - 2y}{3} \\ \\ x - y = 1 \\ x = 1 + y \\ \\ 1 + y = \frac{8 - 2y}{3} \\ 3 + 3y = 8 - 2y \\ - 8 + 3 = - 2y - 3y \\ - 5 = - 5y \\ 5y = 5 \\ y = \frac{5}{5} = 1 \\ y = 1[/tex]
[tex]x = 1 + y = 1 + 1 = 2 \\ x = 2[/tex]
Explicación paso a paso:
[tex]3x + 2y = 8 \\ 3 \times 2 + 2 \times 1 = 6 + 2 = 8[/tex]
[tex]x - y = 1 \\ 2 - 1 = 1[/tex]
espero te sirva
