Question

Determine whether the given ordered pair is a solution of the system.
​(5​,4​)
x−y=1
x+y=

Answer 1

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.
