Starting with
5x + 5y = 9
x = 19/15
y = 8/15
Substituting
5(19/15) + 5(8/15) = 9
5 goes into 15, 3 times so rewrite as
19/3 + 8/3 = 9
Add numerators
27/3
which = 9

5x+5y=9 when x=19/15. And when solved Y=8/15.
-----------------------
5(19/15) + 5(8/15) = 9
-----
19/3 + 8/3 = 9
----
27/3 = 9
----
9 = 9

5x + 5y = 9

5%2819%2F15%29+%2B+5y+=+9 ------ Substituting 19%2F15 for x

cross%285%29%2819%2F3cross%2815%29%29+%2B+5y+=+9

19%2F3+%2B+5y+=+9

19 + 15y = 27 ----- Multipling equation by LCD, 3

15y = 27 - 19

15y = 8
