Hi,
3x+4y=14
2x-3y=-19 

9x+12y=42
<u>8x-12y=-76</u>
  17x = -34
    x = -2   |Always recommend caution with 'signs'
Using: 3x+4y=14 to find y  (either of the original EQs work)
and y = {{{3*(-2) + 4y = 14}}},  4y = 20, y ={{{highlight( 5)}}}

 CHECKING our answer*** 
Using: 2x-3y=-19  
     {{{-2*2 -3*5 = -19}}}
Wish You the Best in your Studies.
