Question 179272
1.{{{-2x+6y=19}}}
2.{{{10x-30y=-15}}}
Multiply eq. 1 by 5 and add to eq. 2,
{{{5(-2x+6y)+10x-30y=5(19)-15}}}
{{{-10x+30y+10x-30y=95-15}}}
{{{0=80}}}
Your equations lead to an untrue statement.
There is no solution. 
These are a pair of parallel lines. 
Since they never meet, there is not solution. 

{{{ graph( 300, 300, -5, 5, -10, 10, (19+2x)/6, (15+10x)/30) }}}
