Answer:

$x = - 3 \: and \: y = - 11$

Step-by-step explanation:

$since \: y = 2x - 5(equation \: 1) \: \\$

$substitute \: for \: y \: in \: equation \: 2 \: (6x + 7 = y)$

$6x + 7 = y \\ 6x + 7 = 2x - 5 \\ collect \: like \: terms \\ 6x - 2x = - 5 - 7 \\ 4x = - 12 \\ x = \frac{ - 12}{4} \\ x = - 3$

$substitute \: for \: x in \: equation \: 1$

$y = 2x - 5 \\ y = 2( - 3) - 5 \\ y = - 6 - 5 \\ y = - 11$
