How can we know whether a given ordered pair is a solution of a system of equations? Select all that apply.

We are going to determine whether the point $\left(5,2\right)$(5,2) is a solution of the system of equations:

$x+y=7$x+y=7

$x-y=3$xy=3

We are going to determine whether the point $\left(4,17\right)$(4,17) is a solution of the system of equations:

$y=6x-7$y=6x7

$4x+3y=67$4x+3y=67
