To determine whether the given ordered pair is a solution of the system, we substitute the values of x and y into both equations and see if they satisfy both equations.
For the first equation, x - y = 1, we substitute x = 5 and y = 4:
5 - 4 = 1
1 = 1
Since the equation is true, (5, 4) satisfies the first equation.
For the second equation, x + y = ?, we substitute x = 5 and y = 4:
5 + 4 = ?
9 = ?
We don't know what the question mark should be because the equation is incomplete. Please provide the complete second equation for us to determine if (5, 4) satisfies the system of equations.
