key idea

A point is a solution to a system of equations if plugging the point into each equation results in a true statement.

solution

In the ordered pair

(

)

1 is the

x-value

and 2 is the

y-value.

In the first equation, replace x with 1 and y with 2.

)

≟

Yes,

Now in the second equation, replace x with 1 and y with 2.
