Many ways to do this, but I think the easiest would be substitution, since x is already isolated in one of them.
So replace x in the first equation with the def. of x from the second. You end up with 6-9y+9y=5
Which is basically 6=5
Your answer is no solution.

subsitute for x
6 – 9y + 9y = 5
combine like terms
6 = 5
NO SOLUTION
or do it this way
x = 5 – 9y
x = 6 -9y
multiply one by -1 and add the two equations together
1+ 0 = 0
1= 0
STILL, NO SOLUTION
