----
Substitute x = 5 and y = 2 into each equation and see if you get two true
statements.
----
2*5-2 = 8
10-2 = 8;;;;;;yes
-------------------------
3*5+2*2 = 20
15+4 = 20;;;;;;;no
============================
(5,2) is not a solution for the system

Is the ordered pair (5,2) a solution to the given equations 2x-y=8 and 3x+2y=20?

Step 1. To determine if (5,2) is a solution substitute x=5 and y=2 into the linear system of equations.

Step 2. For , then which is a true statement.

Step 3. For then which is a FALSE statement.

Step 4. ANSWER: Therefore, (5,2) is not a solution to the linear system of equations.

I hope the above steps were helpful.
