Answer :
(3,5)
1) Let's solve that Linear System by the Substitution Method
I) y=5
II) 2x +2y= 16
2) Plugging into the II equation the first one we'll have:
2x +2(5) = 16 Multiply it
2x + 10 = 16 Subtract 10 from both sides
2x = 16 -10
2x = 6 Divide both sides by 2
x =3
3) Hence, the solution to this system is S={(3,5)}
