What does it mean for $(3, 7)$ to be the solution of a system of two equations?

$(3, 7)$ makes both equations true at the same time

$x = 3$ solves the first equation and $y = 7$ solves the second

$3$ comes from one equation and $7$ comes from the other

$(3, 7)$ makes at least one of the equations true
