To determine the whether the ordered pair satisfies the equation:

⇒ we must plug in the values

⇒ since coordinates are (x,y) ⇒ (2,1)

⇒ there we must plug 2 into the 'x' position in the equation

⇒ and 1 into the 'y' position in the equation

Let's try the first equation:

$3x-y=5\\3(2)-1=5\\6-1=5\\5=5$

Let's try the second equation

$5x-2y=8\\5(2)-2(1)=8\\10-2=8\\8=8$

Thus ordered pair satisfies the following system of equations

Answer: Yes
