)
is an ordered pair of the form )
. That tells us that 
must equal 8 whenever 
is equal to 3.
You can proceed one of two ways:
1. Substitute 3 for in the equation:
\ +\ 5y\ =\ 8)
and then solve for . If you end up with 
then is a solution to the given equation. Otherwise not.
2. Substitute 3 for and 8 for in the equation.
\ +\ 5(8)\ =\ 8)
And then do the arithmetic. If you end up with a true statement, then is a solution to the given equation. Otherwise not.
