Explicación paso a paso:
[tex]2x + y = 10 \\ 2x = 10 - y \\ x = \frac{10 - y}{2} \\ \\ x + y = 6 \\ x = 6 - y \\ 6 - y = \frac{10 - y}{2} \\ 12 - 2y = 10 - y \\ - 2y + y = 10 - 12 \\ - y = - 2 \\ y = 2[/tex]
[tex]x = \frac{10 - y}{2} = \frac{10 - 2}{2} = \frac{8}{2} = 4[/tex]
[tex]2 \times 4 + 2 = 8 + 2 = 10 \\ 4 + 2 = 6[/tex]
espero que te sirva
