ok put 2x-11 in for y in the top equation to start with.
3x-4(2x-11)=19

anonymous · Answer

distribute the 4
3x-8x-44=19
-5x-44=19

anonymous · Answer

solve for x
-5x-44=19
-5x=25
x=-5

anonymous · Answer

then substitute -5 for x in your second equation and solve 
y= 2(-5)-11
y=-10-11
y=-21
and that's it
