Question 348531
1.{{{x+9y=5}}}
2.{{{x=6-9y}}}
Use the substitution method.
Substitute eq. 2 directly into eq. 1 for x and find y.
{{{(6-9y)+9y=5}}}
{{{6=5}}}
Your equations lead to an inconsistency.
There is no solution. 
These are two parallel lines that never meet, so there is no intersection (solution).
