KIM [24]

answer:

$( \frac{1}{7}, 1)$

explanation:

$- 5y = - 5 \\ 7x + 6y = 7 \\ divide \: both \: sides \: by \: - 5 \\ \\ y = 1 \\ \\ 7x + 6y = 7 \\ substitute \: the \: value \: of \: y \: into \: an \\ equation \\ \\ 7x + 6 \times 1 = 7 \\ multiply \: 6 \: to \: 1 \\ \\ 7x + 6 = 7 \\ subtract \: 6 \: from \: both \: sides \\ \\ 7x = 1 \\ divide \: both \: sides \: by \: 7 \\ \\ x = \frac{1}{7} \\ \\ (\frac{1}{7}, 1)$
